Pre-1.35 actually - preferably 1.34_1.

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
#2  0xb78bbb7e in malloc () from /lib/libc.so.6
#3  0xb7a767e8 in operator new () from /usr/lib/libstdc++.so.6
#4  0x0815e7e3 in ?? ()
#5  0x081624c9 in ?? ()

#12 0xb7eb81b3 in start_thread () from /lib/libpthread.so.0
#13 0xb792203e in clone () 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:

../configure \
--with-boost-src=/tmp/boost_1_34_1 \
--disable-optimiz \
--disable-optimiz-arch \

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.

Did you run "make clean" after configuring? Maybe it saw all the files were
up-to-date and didn't recompile anything...

Hi Nicolas.

1/ Have now checked in config.log for -g flag with --enable-debug.
It's OK. Also other checks on compiler options - all OK. I hadn't checked enough
when I reported possible problem - apologies.

2/ Now I've got the hang of the compiler options, stacktrace has more
information.
Compiled with:
../configure \
--with-boost-src=/tmp/boost_1_34_1 \
--disable-optimiz \
--disable-optimiz-arch \
--enable-debug \
COMPILED_BY="Option 5"
