Compiling the following invalid objc testcase results in an ICE:
============================
void foo()
{
struct A a;
a.i;
}
============================
bug1.m: In function 'foo':
bug1.m:3: error: storage size of 'a' isn't known
bug1.m:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in objc_is_public, at objc/objc-act.c:7171
Please submit a full bug report, [etc.]
The following patch fixes the problem for me, but hasn't been bootstrapped yet:
