(In reply to comment #1)
> Same crash, but with vanilla compiler flags and only vanilla C code in the test case:

The crash is the same, but the problem is totally different. In fact, all
unrecognizable insns will crash at this spot.

While the original test is fixed in current mainline (and also covered by the
testsuite), the test from Comment #1 still fails.

I have updated the summary, but please do not hijack PRs.

Looking into it.
