The following program produces incorrect output when compiled with the
current gfortran from the gomp branch, but correct output when run with
current mainline gfortran:
program test
implicit none
character(len=80) :: filename
logical :: file_present
filename="testfile"
inquire(file=trim(filename),exist=file_present)
print *,file_present
end
