Yes, you are right. With CFLAGS and CXXFLAGS="-O2 -fno-inline-small-functions"
it does not crash.
Seems like the answers on stackoverflow apply here too and it's the inlined
functions that use up all the a

Reminds me of bug 92850, which has some instructions for further narrowing down
which gcc optimization triggers the problem. Maybe -fno-inline-small-functions
even works around this one as well?

So I went ahead and tested my theory by setting CFLAGS and CXXFLAGS to "-O2"
and then to "-O1".
First:
CFLAGS: -O2 -Wall -std=c99 -Werror=implicit-function-declaration
-Werror=missing-prototypes -f

Aww I got it wrong. When CFLAGS is not set, mesa is compiled with this:
CFLAGS: -g -O2 -Wall -std=c99 -Werror=implicit-function-declaration
