Hi,

0/ After my previous report that rendering biscuit.pov was OK using own-compiled
Linux Beta 28 on Slackware 12.0, I attempted to render all the examples.
Ran into several segfaults whilst rendering. Similar problems on Kubuntu 8.04.1
Compiling on Kubuntu was quite straightforward. (Iteratively getting missing
libraries!).

1/ I'm getting an inconsistent segmentation fault from Beta 28 on both
Slackware 12.0 and Kubuntu 8.04.1 running
povray-3.7/scenes/portfolio/m_textures.ini
(Kubuntu is running as a VMWare Player guest application)

m_textures.ini is supposed to render 14 frames. Sometimes it segfaults
immediately. Sometimes it renders 2, 3 or 4 frames and segfaults.

Cpu: Intel Core2Duo E6550.
Slackware 12.0: gcc 4.1.2. boost 1.34.1 + 19.12.2007 Critical bug patch.
2.6.21.5-smp #4 SM
Kubuntu 8.04.1: gcc 4.2.3. boost 1.34.1 + 19.12.2007 Critical bug patch.
2.6.24-19-generic #1 SMP

I have tried running it with 1 or 2 threads but get the same segfaults. i.e.
povray m_textures.ini +wt1
povray m_textures.ini +wt2

m_textures.ini is OK with Beta 25b on Linux Slackware 12.0
Also OK with Beta 28 on Win2k and WinXP running as guests in VMWare Player.

I have been able to render most of the examples on Slackware 12.0:
/usr/local/share/povray-3.7/scripts/allscene.sh
/usr/local/share/povray-3.7/scripts/allanim.sh
    But a few of the examples also segfault.
    e.g. povray-3.7/scenes/advanced/wineglass.pov
/usr/local/share/povray-3.7/scripts/portfolio.sh aborts at
povray-3.7/scenes/portfolio/m_textures.ini

On Kubuntu 8.04.1:
   wineglass.pov sometimes segfaults at Width = 320 Height = 240, and sometimes
renders OK!
   biscuit.pov is OK at Width = 640 Height = 480, but segfaults at Width 960
Height = 720

2/ I have tried compiling on Slackware 12.0 with both --enable-debug and
--enable-profile
../configure \
--with-boost-thread=boost_thread-mt \
--enable-profile \
COMPILED_BY="geep"

I am not sure that the --enable-debug and --enable-profile options are working
because:
i) gdb reports: (no debugging symbols found)
ii) config.status contains this line: debug=false

Anyway, attached down the bottom are stacktraces from rendering m_textures.ini.
After the segfault there remains a .pov-state file

3/ After untarring povray-src-3.7.0.beta.25b.tar.bz2 I noticed that there are a
number of directories and their files duplicated inside themselves:
povray-3.7.0.beta.25b/include/include
povray-3.7.0.beta.25b/ini/ini
povray-3.7.0.beta.25b/scenes/scenes
povray-3.7.0.beta.25b/scripts/scripts

4/ On Slackware 12.0 "make check" renders biscuit.pov and displays the image in
a full screen mode. i.e. the image is surrounded by black screen.
This freezes the mouse cursor and keyboard too, and so locks the machine.
Hardware reset is needed to reboot.

Cheers,
Peter

Do you have the correct version of the Boost libraries installed? This
sounds like the threading problem. The docs require pre-1.34

Pre-1.35 actually - preferably 1.34_1.

NB official Linux beta 28 source is now available.

Have now tried the official beta 28 source on Slackware 12.0 with:
i) boost 1.34.1 libraries (that work OK with beta 25b)
ii) boost 1.33.1 libraries
iii) boost 1.33.1 built by povray using option --with-boost-src=

Always segfaults rendering m_textures.ini.
All segfaults look somehat similar, the last 2 entries being start_thread (),
clone ()
Last segfault from iii) above is:
#0  0xb78b7d9a in malloc_consolidate () from /lib/libc.so.6
#1  0xb78ba2c7 in _int_malloc () from /lib/libc.so.6

I would be interested if anybody out there can duplicate these segfaults.
Or suggest what I might be doing wrong...

Cheers,
Peter

	Thanks for your reports and in particular that one -- this is something
I got already while preparing earlier source packages and forgot to check again
lately.  The next beta will get the correct source tree.

This segfaults too:
iv) boost 1.34.1 built by povray using option --with-boost-src=

  It might help if you do this:

1) Reconfigure (or edit the Makefiles) so that optimizations are turned
   off and the compiler option -g is specified.

2) Recompile everything. (May require a clean.)

3) Run the recompiled povray with gdb (ie. "gdb povray" and then from
   the gdb prompt "run scene.pov" or whatever).

4) When it crashes, write "bt" and post the output here.

  (It might be possible that it will not crash because you turned
optimizations off. If that's the case, then try doing all the above
again, but keeping all the same optimizations as your normal compile,
and with the -g option. There's a small probability that the backtrace
is not as reliable this way (because of all the inlining), but it may
still be useful.)

Hi Warp - I assume this is what you meant for configure:
CFLAGS="-g" \
CXXFLAGS="${CFLAGS}" \
../configure \
--with-boost-src=/tmp/boost_1_34_1 \
--disable-optimiz \
--disable-optimiz-arch \
COMPILED_BY="Beta 28 no_optim autocompiled_boost_1.34.1>"

Haven't the knowledge to edit Makefile directly.

	I verified that both --enable-debug and --enable-profile, alone or together,
work as expected.  Please check that configure reports that the -g compiler flag
is working and that the option is effectively used when compiling.
