Bug #: 14583
Summary: Incorrect prototype for sigsetjmp
Product: glibc
Version: 2.17
Status: NEW
Severity: normal
Priority: P2
Component: nptl
AssignedTo: unassigned@sourceware.org
ReportedBy: law@redhat.com
CC: drepper.fsp@gmail.com
Classification: Unclassified
pthread.h declares __sigsetjmp as:
extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROW;
The problem is __sigsetjmp needs to be marked as non-leaf as is the case in
setjmp.h:
extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask)
__THROWNL;
Failure to mark __sigsetjmp correctly can result in GCC eliminating stores that
are not dead. See:

Fixed by adding changing pthread.h's copy to use __THROWNL rather than __THROW.
