Bug ID: 97162
Summary: [11 Regression] ICE when building SPECCPU 2006 Gamess
benchmark
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: tnfchris at gcc dot gnu.org
Target Milestone: ---
Unforunately I don't have data going back to the start of GCC 11 and I also
don't know any fortran so no idea how to go about minimizing this..
But Gamess in SPECCPU 2006 fails with an ICE:

when built with
-Ofast -fomit-frame-pointer -flto --param ipa-cp-eval-threshold=1 --param

Removing any of these options seems to make it go away.
