Hello list

I got some code that have been working fine on Win/Linux/OS X Tiger
for a while now. When I got my new OS X box I got Leopard, and when
trying to build our project it built fine, but it failed to start at
all when i made release mode compiles, but debug mode worked just
fine. It seemed it didnt even get into my main()..
After a number of hours I've narrowed it down to posix_time.hpp and
strip.. Example:

#include <boost/date_time/posix_time/posix_time.hpp>
int main(int argc, char const ** argv) { }

Compiling it (simple jamfile but easier to just paste this)

johan-mp ~$ g++-4.0 -ftemplate-depth-128 -O3 -finline-functions -Wno-
inline -Wall -fPIC -dynamic -Wno-long-double -no-cpp-precomp -
DNDEBUG -I"/Users/johan/boost_1_34_1" -c -o "test.o" "test.cpp"
johan-mp ~$ g++-4.0 -o "test" "test.o"
johan-mp ~$ g++-4.0 -o "test" "test.o"
johan-mp ~$ ./test
johan-mp ~$ strip test
johan-mp ~$ ./test
zsh: bus error ./test
johan-mp ~$ gdb ./test

So, if i remove the #include for posix_time.hpp it works fine. Or if I
skip the strip part....

The GDB output here doesnt give much but the trace from the original
project looks like this:
0x00491c04 in typeinfo name for

(gdb) where
#0 0x00491c04 in typeinfo name for
boost::filesystem::path_traits> >::m_imp> ()
#1 0x00000000 in ?? ()

Doesnt say much either.. I've also managed to get traces like this
(not from gdb but osx crashlog):
0 myapp 0x004af69d 0x1000 + 4908701

dyldbootstrap::start(mach_header const*, int, char const**, long) + 818
7 dyld 0x8fe01037 _dyld_start + 39

The original project was working perfectly fine on OS X Tiger (release
& debug mode), and the tiger build works fine on leopard too, but when
built on my leopard in release mode it fails...

Does anyone have any clues whatsoever what this can be?? boost is
1.34.1 where only change is user-config.jam with
using darwin : 4.0 : g++-4.0 ;

Thank you for any ideas
