Building an Arch package from current git master makes the system unbootable
with just a black screen. We did biscect this and found this commit
(bb4aa6e06ee3877110a1dc0eb0d766ffac978993 in master) to be the first bad one.

As gcc is mentioned in the commit message... We are building with gcc
13.1.1-1. Any idea what is going on here?

"CX:;",b;for(a/*    Best regards             my address:    */=0;b=c[a++];)
putchar(b-1/(/*    Chris            cc -ox -xc - && ./x    */b/42*2-3)*42);}
