It's supposed to be the truncate.
I believe I know what's going on. I've introduced this bug yesterday, of
course. Thomas Huth bisected a problem with an s390 host, and I strongly
suspect that it's the same bug. (I haven't been able to reserve an s390 build
system today to verify.)
Try the tree prior to af3cbfbe8018ccc16fb3a0048e928f66f0d05e87 and see
if things work.
Ho hum. Patch coming soon.
