I can't say that I have used that exact same setup, but I started using 
shared pointers with STL-Containers with varying gcc versions with 64bit 
linux about 1.5 years ago and never ever had a problem with them.

But of course, shared_ptrs do not make everything fail-safe. For 
instance, a shared_ptr could contain NULL. In that case, calling a 
member function of the contained object would result in a segmentation 
fault.

You should try to boil down the problem to a few lines. You will 
probably see the problem then (or you can then ask for more specific help).
