I'm impressed - I'm now up to 3 out of 3 glibc bugs reported and fixed
in the last month (more often than not, I've had the misfortune of my
glibc bugs report attempts being rejected with rather scathing comments
that the bug is not in glibc but in my understanding, or left without a
response for months on end).  Leaving garbage in buf upon strerror_r
failure was one of those fixes.
