--- Comment #1 from Greg Turner <g...@be-evil.net> --- (In reply to Greg Turner from comment #0) > this bug report will be long and confusing tldr: as of 94e24187 host-optimized gcc exhibits ICEs while building complex C++ projects on AMD zen hosts. The problem manifests during gimplification, usually nondeterministically. Reverting 94e24187 resolves the problem, however the ultimate cause is as of yet undiagnosed. Full details in my original long and confusing post :)
