Bug ID: 71859
Summary: ICE on same variable/subroutine name (verify_gimple
failed)
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fort...@t-online.de
Target Milestone: ---
When using the same name for a variable and a subroutine (invalid),
experimental (--enable-checking=yes) versions 7, 6 and maybe older
ones (not tested) give an ICE.
No ICE for release versions 4.9, 5, 6, 7.
