Bug ID: 93907
Summary: internal compiler error: in hashtab_chk_error, at
hash-table.c:137
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
The attached code crashes when compiled with -std=gnu++2a. THe error looks like
it might be related to PR 87847:
