Suggested patch
Specific use case bug found in SysRes VG_(do_sys_sigprocmask)
coregrind/m_signals.c
Fix for case when ,,set,, parameter is NULL.
In this case ,,how,, parameter should be ignored because we are only requesting
from kernel to put current signal mask into ,,oldset,,.
But instead we determine the action based on ,,how,, parameter and therefore
make the system call fail when it should pass.
Taken from linux man pages (sigprocmask).
Suggested patch provided in attachment.
