Bug ID: 98186
Summary: [9/10/11 Regression] ICE tree check: expected
omp_clause, have bit_cast_expr in tsubst_omp_clauses,
at cp/pt.c:17246
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Using testfiles pr94477.C or pr94512.C with option -O0
affects versions down to r9 :
$ g++-8 -c pr94477.C -fopenmp-simd -O0
$ g++-11-20201206 -c pr94477.C -fopenmp-simd -O2
$
$ g++-11-20201206 -c pr94477.C -fopenmp-simd -O0
during GIMPLE pass: ompexp
