proposed patch
I have a fix [already bootstrapped, currently regression testing]. The code in
store_constructor is currently unaware of the C99 semantics of passing
structures
by value containing flexible array members. Andrew's code in comment #5 is
valid (confirming an ICE-on-valid-regression), but Xingbang's function foo in
the original report is broken, as the b array isn't passed, and accessing b[0]
is (I believe) undefined behaviour. Ideally, we should issue some kind of
warning.
