Confirmed, indeed looks like a dup of that PR.

Looks like it's a separate thing from PR102385, but caused
by the same commit (g:62acc72a957b5614)

No longer ICEs for me, but the fixes I'm aware of shouldn't have affected it.
What fixed it?

Started to ICE with r12-3876-g4a960d548b7d7d942f316c5295f6d849b74214f5
Stopped ICEing with r12-5264-gd1ca8aeaf34a717dffd8f4a1f0333d25c7d1c904
I think we want the testcase for the testsuite in any case.
