            Bug ID: 114034
           Summary: Failure of tests gcov-dump-{1,2}.C
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fxcoudert at gcc dot gnu.org
  Target Milestone: ---

We have the following failures on x86_64-apple-darwin23:

FAIL: g++.dg/gcov/gcov-dump-1.C  -std=gnu++98 (test for excess errors)
FAIL: g++.dg/gcov/gcov-dump-1.C  -std=gnu++14 (test for excess errors)

Excess errors:
ld: warning: ignoring duplicate libraries: '-lgcov'

The compilation line only includes one -lgcov:

but the driver somehow includes another one when calling collect2:

I'm wondering if it's a good idea to simply ignore the warning in the two test
cases. It's not such a frequent use case, and darwin linker to being a pain
here.
