This isn't the only testcase that started failing recently.
One interesting flag combination:
$ gcc -O2 -fno-tree-ccp -fno-tree-copy-prop -fno-tree-dce testcase.c && ./a.out
Segmentation fault
In this case, the body of main() isn't generated at all, so the code runs away
immediatelly after jumping to main().
main:
.LFB2:
.cfi_startproc
.cfi_endproc
.LFE2:
.size main, .-main
