Lwp_sea_wait hang

Question

Hi - can anyone help please !
I have a large program that hangs on exit. The optimized (-fast) version has the problem - the non-optimized version does not. I believe the code is calling the destructor for a std::set< std::pair< enum, std::string > I have been unable to duplicate the problem in a smaller test harness.
This is built using :
CC: Sun WorkShop 6 2000/08/30 C++ 5.1 Patch 109490-01
the stack is as follows:
using M,P to clarify the stack...
M=std::pair<myNameSpace::MyClass::MyEnum,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >
P=__rwstd::__rb_tree<M,M,__rwstd::__ident<M,M >,std::less<M >,std::allocator<M > >
