Does anyone know what might MAY> be going on here, or how I might debug it further? I see similar problems, but unrelated to 'halt'. They appear ocasionally. And are very much like that problem you reported earlier (about copy from user). It happens in the same place for me, Jeff's patch that converts *jmp() calls to sig*jmp() is present in my tree. Jeff: I finally hit the problem yesterday with extra debug code to save the sigmask. Here's what I see. (also include sigjump buffer that was setup later than sigprocmask was run). sigmask = {__val = {134284288, 0, 0, 0, 134284288, 0, 23441, 0 , 2776382020, 0, 2776381980, 2685736023, 2776382020, 0, 2776382020, 2776382172, 2685229112, 0, 0, 0, 2776382068}} jbuf = {{__jmpbuf = {-1518585548, 800, -1607600160, -1518585268, -1518585740, -1609727948}, __mask_was_saved = 1, __saved_mask = {__val = {134284288, 0, 2776382332, 2776382324, 1, 2776382372, 2776382372, 0, 14, 7, 2685735890, 115, 642, 2776382324, 123, 0, 134284288, 135492232, 1, 8, 2776367104, 2776381732, 2685239162, 29, 2776381744, 0, 0, 0, 0, 2776382476, 2685735368, 29}}}} Bye, Oleg ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
