[Bug c/38346] New: NTPL pthread_create is thread safe ?

["deadmaxfr at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Dears,

I'm currently develop a multi-threaded application using GCC pthread (NTPL).

My application start a thread who start another sub-thread.

During the creation of the subthread, i invoke the pthread_cancel on the first
thread. This result sometime a Sigfault (see the diagram bellow).

Main thread
     |
pthread_create (thread 1)
     |
pthread_create (finish)          Thread 1
     |                              |
     |                        pthread_create (thread 2)
pthread_cancel (thread 1)           |                     => Segfault ?
     |                              |
     |                              |
     V                              V

I'll try to post some sample code today.

Regards,

Alexandre Martins
