Summary: [4.7/4.8 Regression] ICE: in get_expr_operands, at
tree-ssa-operands.c:990 with lambda function

Status: UNCONFIRMED
Severity: normal

GCC 4.8 needs -fkeep-inline-functions to crash, 4.7 doesn't need any special
argument; 4.6 accepts the code fine.
Compiler output - 4.8:
$ gcc -fkeep-inline-functions tmp.ii
