--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> ---
I also cannot reproduce the ICE with the original test case but I can confirm
it with the test case from comment #6. The test case isn't strictly conforming
(as pointed out by a number warnings when -Wall is used). Resolving the
problems (declaring fn5, adding the missing return statements, or initializing
the local variables a in fn3) makes the ICE disappear.
The problem was introduced in r219854:
