Dear, all #include int main () { int p; sem_t sem; int i=0,d; //sem=(sem_t)NULL; //With this There isn't any problem sem_init (&sem,0,1); sem_post (&sem); sem_wait(&sem); return i; } cygwin 1.3.17-1 gcc 3.2-3 gdb 20010428-3 When executing this source code with gdb I get an SIGSEGV signal when sem_init() function is called. If I continue on, program works fine. If program is not executed from gdb, it works without any error. If I initialize it with NULL, I don't get any error. I think that is the same behavior as described by following mail: http://sources.redhat.com/ml/cygwin/2002-10/msg00956.html Is this true ? To avoid annoying gdb error message, is my solution ("sem=(sem_t)NULL") reliable and portable ?
