            Bug ID: 65112
           Summary: [5 Regression] -fsanitized=thread Fortran program
                    crashes at startup
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Joost.VandeVondele at mat dot ethz.ch
                CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
                    jakub at gcc dot gnu.org, kcc at gcc dot gnu.org

Current trunk leads to segfault with:

> cat main.f90 
END

> gfortran -fsanitize=thread -fopenmp -gdwarf-3 -fPIE -pie -fno-omit-frame-pointer main.f90 ; ./a.out
Segmentation fault

the same goes fine with 4.9

gdb yields:

Program received signal SIGSEGV, Segmentation fault.

Can't reproduce, works just fine here.
