The segfault looks like a memory corruption problem (or my GDB is nuts), so 
I'll leave it to someone else.

-fpack-struct is not compatible with libstdc++-v3. For once, you should have 
compiled the library itself with -fpack-struct, otherwise you are going to get 
segfaults at runtime due to different object layout. 

A good solution could be to make -fpack-struct affects only user-defined 
structures. This could be a check for structs defined in system headers or in 
namespace std (which is reserved anyway). I will submit a patch to change the 
behaviour of -fpack-struct once the segfault is solved.
