I've just moved our project across to Boost 1.33, which seems to be
working fine on our x86 linux gcc 3.4.4 machine. However, I'm getting
seg faults on really basic stuff on the mac G5 we have, running linux
with gcc 3.4.4 (Gentoo, using ppc64 kernel and userspace). This machine
had no problems under Boost 1.32, I should add.
Here is a simple test program (based on one of the early examples):
=========
#include
namespace po = boost::program_options;
int main ( int, char* )
{
po::options_description generic("Generic options");
generic.add_options() ("version,v", "print version string");
generic.add_options() ("help", "produce help message");
return ( 0 );
}
=========
The seg fault happens on the second add_options() line. If the two lines
are combined (as in the original example) it faults somewhere in there,
but I think it is the same place.
My gdb session:

=========
Any advice or suggestions are welcome.
We're installing boost 1.33 in our 32-bit ppc chroot environment, and
will see if there is any difference there, in case that helps.
Also it is worth noting that we have a program that doesn't use the
program_options, but does use boost filesystem, and that seems to run
fine.
Take care,
Liam
