Bingo! We're on the right track. sigprocmask is *definitely* the wrong thing to call here, and would explain your symptoms. Can you please send the preprocessed output of pthread_sigmask.c? That is, if 'make' uses the following command to build pthread_sigmask.o:
gcc -std=gnu99 -DHAVE_CONFIG_H -I../src -g3 -O2 -c pthread_sigmask.c then please send the output of: gcc -std=gnu99 -DHAVE_CONFIG_H -I../src -g3 -O2 -E pthread_sigmask.c It may be large; OK to send it as a compressed attachment. Thanks.
