If it exits printing a nonzero value of the volatile variable x, this means the signal handler wrongly executed under asynchronous cancellation. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
