Hmm, I get a similar failure (reported ~1 week ago) on glibc-2.0.106
powerpc-unknown-linux-gnu. The core dump showed that cpp crashed in
fileno_unlocked, because fileno_unlocked was handed a NULL (? no longer
100% sure about that) pointer. I thought cpp got miscompiled on PPC cause
the contruct looked so simple: fileno(stdout). But now I'm no longer sure
about that.
