[Patch, fortran] PR83149 [8 Regression] ICE on SELECT CASE: crash_signal in toplev.c:325

[Paul Richard Thomas]

Hi All,

The original bug is fixed as 'obvious' in revision 257938. This is
indeed a regression.

The bug in comments 2 and 7 is fixed in revision 257934. This,
however, is not a regression. The summary will be changed accordingly.

The 'obvious' tag comes about because both bugs have a common origin:
referencing the components of ns->proc_name without testing to see if
it is there.

Should I close this or should I apply the second part to 7-branch?

Cheers

Paul
