Bug ID: 78571
Summary: ICE in create_character_initializer, at
fortran/data.c:191
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: ---
With invalid code, down to at least 4.8 (with --enable-checking=yes).
A different facet; ICE does not depend on compile options, nor on locale.
Potentially related to pr70070.
