Dominiq, thanks for tracking this down. So the example code in this
otherfortran manual is invalid. I noticed a few other examples in there that
are obfuscated in some manner to not be valid. I am sure just ed

In case of Fortran 95 it is trivially invalid (cf. comment 3 and comment 5).

I think the problem is here (around line 706 in the last commit):
if (t == FMT_F || t == FMT_EN || t == FMT_ES || t == FMT_D
|| t == FMT_G || t == FMT_E)
{
repeat = 1;
goto

ahh, I was looking at the F2003 Standard which is not as clear. However, is
this relaxation in F2003 done on purpose? I found the rejected code in the IBM
compiler manual as an example.

I assumed i was an integer. F95 says:
Constraint: If the optional characters FMT= are omitted from the form

In the original test case:
real :: i
The part that is rejected incorrectly is the format label.

The F95 standard says:
The F, E, EN, ES, and D edit descriptors specify the editing of real and
complex data.
An input/output list item corresponding to an F, E, EN, ES, or D edit
descriptor shall be real or complex
