Hmmm... looks like the strerror issue it could be a serious bug:
#include <errno.h>
#include <stdio.h>
#include <sys/stat.h>
int
main()
{
struct stat sb;
int o_errno;
if (stat("/some/file/that/doesn't/exist", &sb) != 0) {
o_errno = errno;
printf("Errno: %d\n", errno);
err(errno, "%s", strerror(o_errno));
}
return 0;
}
[gcooper at optimus ~]$ ./badfile
Errno: 2
badfile: Segmentation fault: 11 (core dumped)
I rebuilt my kernel and installed it, and I rebuilt world, but
haven't installed it yet though, so let me reboot the amd64 machine
and see what happens (may be a mismatched ABI issue)...
Cheers,
