C source code
I just tried to compile the package jam-2.5-14
on gcc-4.9 trunk dated 20130425 on an AMD x86_64 box.
The compiler said
execunix.c: In function 'execcmd':
execunix.c:322:1: error: control flow in the middle of basic block 10
}
^
execunix.c:322:1: error: control flow in the middle of basic block 10
