Bug ID: 90939
Summary: ICE in meet_with, at ipa-cp.c:1073
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: jamborm at gcc dot gnu.org, marxin at gcc dot gnu.org
Target Milestone: ---
I see the ICE in chromium package with gcc9 package.
It won't be so easy to reduce a test-case, I ended up with 15 object files.
I can reproduce that with 72fa547fbac7c8dc58c5caf53e35d4b68432c08c revision and

So it's a MAX_EXPR with a pointer_type:
