Bug ID: 93268
Summary: ICE with gcc-10 when compiling hypre library with -O3
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: kristopher.kuhlman at gmail dot com
Target Milestone: ---
I am building petsc, and the hypre library being built as part of that triggers
this ICE when using optimization. When building the same library with -Og there
is no ICE.
This library didn't trigger this ICE with a gcc version from a month or two
ago, so this is maybe due to a recent change?
I created a pre-processed version of the relevant source file, but it is
enormous (12k lines). I can attach it if desired.
