It's an lvalue-cast, which we no longer support as an extension. So it's ICE on
invalid and a frontend bug. The C++ frontend spits out the interesting error
pr23155.c: In function void foo5(int):
pr23155.c:7: error: no matching function for call to vx::vx(int&)
pr23155.c:1: note: candidates are: vx::vx()
pr23155.c:1: note: vx::vx(const vx&)
The following get's rejected with what should be done with the original
testcase, too:
union vx {short f[8]; int v;};
int vec;
void bar(short *);
void
foo5 (int vec)
{
bar(((union vx) vec).f);
}
pr23155.c: In function foo5:
pr23155.c:10: error: invalid use of non-lvalue array
