I have applied another obvious patch to fix this PR. It was tempting to
remove both gcc-asserts but I have erred on the side of caution this time.

Commit r11-6924-g003f0414291d595d2126e6d2e24b281f38f3448f

Again, it is sufficiently safe and obvious that I am tempted to put it on
my list of backports.
