It looks like that SIGABRT does not call the callback, but crashes the process. > unstable9s% gdb test-sigaction > GNU gdb (GDB) 7.4.1 > Copyright (C) 2012 Free Software Foundation, Inc. > License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> > This is free software: you are free to change and redistribute it. > There is NO WARRANTY, to the extent permitted by law.

() On test-raise.c for some obscure reason SIG_ERR is ( void ( * ) ( ) ) 0 which then fails the assert as "0" usually means no error. This is because "lint" is defined: > ../config.log:#define lint 1 and hence in /usr/include/sys/iso/signal_iso.h this breaks: > #elif defined(lint) > > #define SIG_DFL (void(*)())0 > #define SIG_ERR (void(*)())0 > #define SIG_IGN (void (*)())0 > #define SIG_HOLD (void(*)())0 > > #else > > #define SIG_DFL (void(*)())0 > #define SIG_ERR (void(*)())-1 > #define SIG_IGN (void (*)())1 > #define SIG_HOLD (void(*)())2 > > #endif Undefining "lint" in lib/config.h makes this test pass immediately. Hopefully this helps.
