--- Comment #1 from Linus Torvalds <torvalds@linux-foundation.org> ---
Side note: it might be best to clarify that this is a regression specific to
gcc-12.

Gcc 11.3 doesn't have the problem, and generates code for this same test-case
with a stack frame of only 428 bytes. That's still bigger than clang, but not
"crazy bigger".
