1/ I still get segfaults rendering m_textures.ini (see below) in a different
environment, after changing from Slackware 12.0 to Slackware 12.1,
using official beta 28 source and precompiled repository
(http://repository.slacky.eu/slackware-12.1)
versions of libraries: boost-1.33.1 icu-3.6 ilmbase-1.0.1 openexr-1.6.1
But beta 25b renders m_textures.ini fine using exactly the same ./configure
options and installed libraries.

I had patched the 1.34.1 source as per http://boost.sourceforge.net/
December 19, 2007 - Critical Bug in Function Library
* Boost.Function in Boost 1.34.x has a bug that affects the construction of
Boost.Function objects in a multi-threaded context. The problem has been fixed
in the Boost trunk and for the upcoming Boost 1.35.x. To patch your Boost
1.34.x, copy the files function_base.hpp and function_template.hpp into the
Boost directory boost/function.

3/ I'd previously had similar segfaults on Kubuntu with boost 1.34.1
downloaded from Kubuntu repository, using --with-boost-thread=boost_thread-mt
configure option.
4/ Am I still the only person to see these segfaults on Linux?
I've now tried installing on 3 different Linuxes and always get the
same segfaults. I suppose I could be making the same mistake in all 3 OS's,
but as the last test only involved compiling Povray (./configure shown above)
and installing 4 pre-compiled packages (using simple Slackware command
"installpkg packagename.tgz") the opportunity for even me to screw-up is
limited!

Operations seems to SigSegV on memory allocation/release
(first is on pixels.reserve(pixels.size()*5), with pixels.size()==1024)
second is on pool.push_back(ptr); on destroy of Ref object,
third is on vector<double> rands(count); with count==32768 )
first was done with -WT1, second & third without...
Either that, or the C++ memory allocator/deallocator is not thread-
safe... or the one in libc.6 (missing an option for malloc thread-safe ?)
gcc (GCC) 4.2.4
