[Bug libc/221] New: C++ throw terminates ucontext_t context, instead of returning via uc_link

["a dot darovskikh at compassplus dot ru" <sourceware-bugzilla at sources dot redhat dot com>]

When an exception occurs in another execution thread 
created with makecontext(), it causes program to exit 
with SIGABRT, instead of being catched in the main thread. 
 
Returning from this function works OK. I use recent GCC (3.4.0), 
and, as far as I understand, the problem is somewhere inside 
_Unwind_RaiseException, which doesn't check if it's another context. 
 
The test case is included.
