[Bug middle-end/27382] New: [4.2 regression] ICE in c_common_truthvalue_conversion with label address

[reichelt at gcc dot gnu dot org]

The following valid code snippet causes an ICE on mainline:

======================
void foo()
{
    L:
    !&&L;
}
======================

bug.c: In function 'foo':
bug.c:4: internal compiler error: tree check: expected tree that contains 'decl
with visibility' structure, have 'label_decl'  in
c_common_truthvalue_conversion, at c-common.c:2503
Please submit a full bug report, [etc.]

void foo()
{
    L:
    &&L != 0 ;
}

Most likely also fails but is done in a different place.
PARM_DECL has the same issue but I already filed/fixed them.
