account. Unfortunately, Perl assumes that the stat buffer contains all
the necessary information, and passes it, instead of the filespec, to

+the access-checking routine. It will try to retrieve the filespec using
the device name and FID present in the stat buffer, but this works only
if you haven't made a subsequent call to the CRTL stat() routine,
because the device name is overwritten with each call. If this warning

only if some internal code takes stat buffers lightly.)
