pthread_cancel/gcc bug?

[jfranzoy]

Hello.
I detected that a program aborts if pthread_cancel is issued under certain circunstances :

• if the target thread is blocked in a call to select in a member function with ' throw()' exception especification (throw nothing).
• if the target thread is blocked in a call to select surrounded by a try/catch(...) block that do not rethrow.

My question is, ¿is this behaivour correct?
In pthread_cancell_examples.zip, there are two code samples and the output of g++ -v and uname -a.
Thanks a lot .

Gcc team is aware of the problem. Link to gcc bug report is Bug 28145 - C++ (throw() and catch(...) {/* fall through */ } ) and pthread cancellation are incompatible (at least with NPTL)
