            Bug ID: 103823
           Summary: g++.dg/torture/pr31863.C fails on darwin with "using
                    serial compilation of 2 LTRANS jobs"
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

g++.dg/torture/pr31863.C fails on *-apple-darwin with:

FAIL: g++.dg/torture/pr31863.C   -O2 -flto  (test for excess errors)
Excess errors:
lto-wrapper: warning: using serial compilation of 2 LTRANS jobs

Not sure if the message is expected or not, if there is a bug to fix (or if=
 we
need to find a way to silence the testcase on darwin).=
