Yes, confirmed it was indeed a bug:
$ gcc -Wall -Wextra -pedantic -std=c11 -o bin/infunc2 infunc2.c
And, with Jelle van der Waa's suggestion, I loaded clang (which I never
otherwise install) and it confirms the issue further:
$ clang -Wall -Wextra -pedantic -std=c11 -o infunc2 infunc2.c
The only part I'm unclear on is where in the fix process
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84607 is on getting fixed and
when that will trickle down to us.
