            Bug ID: 103369
           Summary: [12 Regression] gfortran.dg/vector_subscript_1.f90
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: msebor at gcc dot gnu.org
  Target Milestone: ---

I see the following unexpected failures with today's build of GCC 12:

FAIL: gfortran.dg/vector_subscript_1.f90   -O1  execution test
FAIL: gfortran.dg/vector_subscript_1.f90   -O2  execution test
FAIL: gfortran.dg/vector_subscript_1.f90   -O3 -fomit-frame-pointer
-funroll-loops -fpeel-loops -ftracer -finline-functions  execution test
FAIL: gfortran.dg/vector_subscript_1.f90   -O3 -g  execution test
FAIL: gfortran.dg/vector_subscript_1.f90   -Os  execution test

The output just before each failure looks like this:

Execution timeout is: 300
spawn [open ...]
STOP 12
FAIL: gfortran.dg/vector_subscript_1.f90   -O1  execution test

I didn't investigate beyond that so I don't know if the problem is in the front
end or elsewhere.  The test hasn't changed since February 2018 so I'm guessing
it's not the cause of the problem.

I think this is the same as PR 102043 as described in PR 86389 .

This is tracked as PR102043 (it is long lasting bug which was earlier
manifesting itself only with -fipa-pta, but now it also gets exposed by modref)
