The bug was accidentally found by the following program: #include <asm/sysinfo.h> #include <asm/unistd.h> #include <sys/syscall.h> static int setsysinfo(unsigned long op, void *buffer, unsigned long size, int *start, void *arg, unsigned long flag) { return syscall(__NR_osf_setsysinfo, op, buffer, size, start, arg, flag); } int main(int argc, char **argv) { short x[10]; unsigned int buf[2] = { SSIN_UACPROC, UAC_SIGBUS, }; setsysinfo(SSI_NVPAIRS, buf, 1, 0, 0, 0); int *y = (int*) (x+1); *y = 0; return 0; } The program shoud fail on SIGBUS, but didn't. The patch is a second part of userspace flag fix (commit 745dd2405e28 "Alpha: Rearrange thread info flags fixing two regressions"). Deleted outdated out-of-sync 'UAC_SHIFT' (the cause of bug) in favour of 'ALPHA_UAC_SHIFT'.
