Hi group,
1/ Trying POV-Ray 3.7.0.beta.25 on Slackware 12.0 with 2.6.21.5-smp kernel,
Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz stepping 0b
I get a Segmentation fault with every .pov file I try, but which run fine
with Povray 3.6. Even a completely empty .pov causes the Segmentation fault.
The dialog ends with:
Library paths:
/usr/local/share/povray-3.7
/usr/local/share/povray-3.7/ini
/usr/local/share/povray-3.7/include
==== [Parsing...] ==========================================================
Segmentation fault
2/ BUT povray --version, povray --help and povray --benchmark all run OK.
I attach the entire dialgue from --benchmark below.
3/ Anybody else having this problem?
Any suggestions how to solve?
4/ I have tried this on 2 different Slackware 12.0 installations on the same PC.
In the first I installed it as user (to avoid getting tangled with existing
Povray 3.6).
In the second I installed it as root (no existing Povray installation).
But get the same problem with both.
5/ Had a lot of enjoyment using Povray, and looking forward to getting both my
cores rendering.
Cheers,
Peter

POV-Ray 3.7.0.beta.25 (icpc 10.1 @ i586-pc-linux-gnu)
Entering the standard POV-Ray 3.7 benchmark version 2.01.
This built-in benchmark requires POV-Ray to be installed on your system
before running it. There will be neither display nor file output, and
any additional command-line option except setting the number of render
threads (+wtN for N threads) and library paths (+Lpath) will be ignored.
To get an accurate benchmark result you might consider running POV-Ray
with the Unix 'time' command (e.g. 'time povray -benchmark').
The benchmark will run using 2 render thread(s).
Press <Enter> to continue or <Ctrl-C> to abort.

Maybe a stacktrace would help developers track it down; although I don't
know if it's compiled with debugging information.
If you were running povray as:
$ ./povray -Isomefile.pov +w640 +h480 -whatever-other-options
Try this:
$ gdb povray
(gdb) set args -Isomefile.pov +w640 +h480 -whatever-other-options
(gdb) run
Wait for the segfault, and type 'bt' on the (gdb) prompt.

Mon Dieu, that was a quick response!
Don't think there's any useful debug info.
For what it's worth I had tried gdb and strace - they gave me:
