That's it. Any ideas what it means and how I should compile the povray?

Thanks!

	You might try configuring povray so as to include debug information
and run it under a debugger:

./configure COMPILED_BY=you --enable-debug
make
gdb ./unix/povray
run test.pov options
bt

	and report the result.

Yes, I tried all options and cases I could imagine. GCC works fine, either
with optimizations or without it. However ICC doesn't whatever option or
switches combination I used. I suppose the problem is in the libcxa intel
library. Still trying to investigate this hypothesis.

BTW, when the multithreading version of the POV-Ray will be availabe for
UNIX machines like mine?

Yes! Finally I solved the problem. It was really a problem of
incompatibility between gcc and intel libraries. So, to obtain working
binaries the
LDFLAGS="-cxxlib-icc -lcxa" should be supplied for the configure.

Result is pretty good, look at gcc vs icc timings:

Total Scene Processing Times
  Parse Time:    0 hours  0 minutes  0 seconds (0 seconds)
  Photon Time:   0 hours  0 minutes  4 seconds (4 seconds)
  Render Time:   0 hours  1 minutes 46 seconds (106 seconds)
  Total Time:    0 hours  1 minutes 50 seconds (110 seconds)

Total Scene Processing Times
  Parse Time:    0 hours  0 minutes  1 seconds (1 seconds)
  Photon Time:   0 hours  0 minutes  4 seconds (4 seconds)
  Render Time:   0 hours  1 minutes 13 seconds (73 seconds)
  Total Time:    0 hours  1 minutes 18 seconds (78 seconds)

Almost 1.5x speedup!

  Which version of gcc? Did you compile a 32-bit or a 64-bit binary with it?

Only 64-bit. It wouldn't even possible to compile 32-bit binaries on
Itanium.

  I think gcc4 has better support for 64-bit code.

Ok, thanks. I will try it, however I am not sure it can compete with Intel
compiler anyway.
