[patch, fortran] PR30779 incomplete file triggers ICE

[Jerry DeLisle]

:ADDPATCH fortran:

Hi All,

This trivial patch checks if an end of file occurred after the advance_line is 
called.  The ICE results when trying to access a locus which is NULL in this 
situation.  The solution is to simply jump out.  Allowing other error processing 
to occur.

Regression tested on x86-64 Linux.

I will commit to trunk under the obvious rule.

Regards,

Jerry
