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.
