Bug ID: 122939
Summary: new tests omp-4_a.C and omp-4_b.C fail to compile
Product: gcc
Version: 16.0
URL: https://linaro.atlassian.net/browse/GNU-1768
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: nshead at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Target: aarch64 x86_64
Seen on aarch64, but there were also reports on x86_64: since these new tests
were introduced (r16-5727-g858f30072783), they are causing an ICE on aarch64:
