Hi Nick, that patch looks exactly like my first attempt to fix this bug. I
forget the details now but I'm fairly certain it wasn't a complete fix, which
is why I didn't submit my patch

I believe Eric's comment
http://gcc.gnu.org/ml/gcc-patches/2013-05/msg00179.html points at the correct
fix, but it's a bit messy. You need to recursively descend both decl and
init

Jakub, you're correct. I should have read the standard on flexible array

me.

No, not quite. SECONDARY_MEMORY_NEEDED_MODE looks to be required by lra, so
make rs6000_secondary_memory_needed_mode depend on lra_in_progress.

No, cancel comment #1, I was fooled by version skew between the unpatched and
the patched compiler. The testcase doesn't ICE on recent versions of gcc.

--- Comment #3 from Alan Modra amodra at gmail dot com ---
The testcase doesn't ICE since 206639. That wasn't an rs6000 patch so we
probably still have the underlying issue in the rs6000 backend.
