[Boost-users] Shared_Ptr problem with 1.30.2 and gcc 3.2.3

I've been using shared_ptr's for a while now with gcc 3.1 and recently 
had to upgrade to gcc 3.2.3. Ever since then I'm getting strange crashes 
when shared_ptr's are destructed. Heres a backtrace :
Program received signal SIGSEGV, Segmentation fault.

I am constructing the shared_ptr's in a normal way :
    HullLoader.reset(new HullXMLLoader()); for instance. It seems to 
segfault when delete is called either with the default deleter or with 
one of my own. This was working fine when using gcc 3.1, do I need to 
upgrade my boost or use some compile flag?
Any help would be greatfully appriciated,
Joshua.
