Bug ID: 91524
Summary: [10 regression] module_comm_dm.fppized.f90 in cpu 2017
ICEs in fortran compiler starting with r274551
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at gcc dot gnu.org
Target Milestone: ---
Starting with revision r274551 we began to see the following failure when
building the cpu 2017 test 521.wrf_r. Note that in order to get this to not
generate fortran compilation errors I had to add -std=legacy as per pr91473.
It was definitely r274551 as 521.wrf_r builds fine with r274550.
