           Summary: [8/9 regression] FAIL: gfortran.dg/pr51434.f90   -O1
                    execution test
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3

The test crashes at -O1, but not on other opt levels.  The offset from
.LANCHOR0 is miscalculated for the A.1.2066 object, at -O1 there is another
object (c.2059) placed before it.

-O2 vs -O1:
