Re: luabind and g++ 4.7

Hi, 

thanks for the answer. Sorry for the so few details and so vague message last
time. Here are more details.

Compilation works fine under both versions of compilers (CXX exported to the
correct g++ file).
The program crashes when running after being compiled with g++ 4.7.
Here below a backtrace.

But what's annoying me here is that gdb uses the wrong files (here files from
g++ 4.6 whereas the program was _really_ compiled with g++ 4.7).

Program received signal SIGSEGV, Segmentation fault.

Unfortunately this isn't very much information to go on. Does it fail at compile time or runtime? Are any warnings or error messages printed?

Hello, 

my program using luabind stopped to work when compiled with g++ 4.7. 
If I switch back to g++ 4.6 it works again. 

Is it a know issue ? 

For the moment it is not easy for me to know where exactly the thing 
hurts.
