This is misleading.  What needs to be checked is the size of the *kernel* stat.
See https://gcc.gnu.org/ml/gcc-patches/2018-03/msg01263.html where I fixed it
correctly and explained the issue.  I'm guessing a later import unfixed it, but
I'll go check.

I'm changing the related version (8.0.1 -> 8.1.0), as from the comments it
seems obvious that this is 8.1.0 (and later, presumably?), not 8.0.1.
