--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Are you sure your gcc isn't configured with --enable-checking=release ?
I really get:
pr58248.c: In function ‘main’:
pr58248.c:14:1: error: definition in block 2 follows the use
 main ()
 ^
for SSA_NAME: _126 in statement:
c.2_78 = _16 & _126;
pr58248.c:14:1: internal compiler error: verify_ssa failed
