Description Jerry DeLisle 2008-05-01 03:04:53 UTC

show_locus is failing to show the error locus because for some reason filename_from_unit is returning a NULL string for this test case.

character(len=10) :: cc = 'bad'
open(99,file="dd",encoding=cc)
write(*,*) 'HELLO'
end

Comment 1 Jerry DeLisle 2008-05-01 04:40:03 UTC

The unit has not been opened yet when this error occurs so it does not exist in the unit list yet.  In this case we should just show the unit number.
