I turned my code back to as it was before : instead of using a threaded signal handler, I'm using again a handler defined by sigaction. This works fine with libpthread, but not with libthr on a 5.3 machine. I'm doing some more changes, as before defining signal handling, the application "daemonizes" : forks twice, close and redirect stdin, stdout, stderr, ... and so. Removing this, the application beguns to work but there are still problems. So, I'm getting a test machine to install FreeBSD 6 and debug it. But, what's the relations between pre and after 5.3 libpthreads ? What about libptl2 and libthr ?
