Syscall param rt_sigaction(act->sa_mask) points to uninitialised byte(s) at 0x388520F85A: __libc_sigaction (sigaction.c:64) by 0x468161: busfault_init (busfault.c:145) by 0x46E09A: OsInit (osinit.c:191) by 0x43A3EA: dix_main (main.c:163) by 0x3884A21D64: (below main) (libc-start.c:285) Address 0xffeffedd8 is on thread 1's stack
I can't think of a reason to block any other signals while this is running - both SIGALRM and SIGIO should be harmless here - so just set the mask to empty.
