Bug ID: 108427
Summary: bitfield tests fail with missing warnings
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: nightstrike at gmail dot com
Target Milestone: ---
Both bitfield-3.m and bitfield-5.m appear to fail for the same reason on
x86_64-w64-mingw32 (cross compiled from linux, if it matters). The tests each
contain multiple tests for warnings, only one of which is missing in each case:
PASS: objc.dg/bitfield-3.m -fgnu-runtime (test for warnings, line 20)
FAIL: objc.dg/bitfield-3.m -fgnu-runtime (test for warnings, line 27)

There are similar tests and failures for objc++, but maybe these are supposed
to be XFAIL'd due to PR23610:
