The following reply was made to PR bin/31661; it has been noted by GNATS. From: Craig Rodrigues <rodrigc@crodrigues.org> To: freebsd-gnats-submit@FreeBSD.org Cc: nb@ravenbrook.com, mps-staff@ravenbrook.com Subject: Re: bin/31661: pthread_kill signal handler doesn't get sigcontext or ucontext Date: Mon, 2 Feb 2004 16:39:30 -0500 Hi, I just tried your test program on FreeBSD-CURRENT. When linked with -lc_r, the output is: NSI Thread 0x0804c400 BSD Thread 0x0804cc00 Posix Thread 0x0805f000 waiting for the threads to be alive ANSI is alive: 0x0804c400 BSD is alive: 0x0804cc00 Posix is alive: 0x0805f000 waiting for the signals to be delivered ANSI: Handled 1 signal 30 pthread 0x0804c400 BSD: Handled 1 signal 31 pthread 0x0804cc00 code 0 sigcontext 0x00000000 Posix: Handled 1 signal 25 pthread 0x0805f000 info 0x00000000 context 0x00000000 When linked with -lpthread, the output is: ANSI Thread 0x08053400 BSD Thread 0x08053600 Posix Thread 0x08053800 waiting for the threads to be alive ANSI is alive: 0x08053400 BSD is alive: 0x08053600 Posix is alive: 0x08053800 waiting for the signals to be delivered ANSI: Handled 1 signal 30 pthread 0x08053400 BSD: Handled 1 signal 31 pthread 0x08053600 code 0 sigcontext 0xbfaddbe8 Posix: Handled 1 signal 25 pthread 0x08053800 info 0xbfacdb58 context 0xbfacdbe8 You mentioned that the bug is demonstrated by the fact that sigcontext and context are 0 in the last two lines of the output. This problem does not seem to exist for the new pthread library. -- Craig Rodrigues rodrigc@crodrigues.org
