g77 core dump on outputing namelist (egcs-971105), Redhat Linux 4.2Alpha

[Toon Moene <toon at moene dot indiv dot nluug dot nl>]

Hi,

We (the GNU Fortran bug list) got the following bug report;  
unfortunately, without an Alpha at hand we cannot do much about it  
(it probably is an error in libf2c.a like the one diagnosed by  
Richard Henderson before):

>  When the following code is compiled with the egcs version
>  of g77 (971105) snapshot, under Alpha Linux (RedHat 4.2
>  Linux 2.0.30 kernel), it crashes with a Segmentation
>  fault(core dumped), apparently associated with the

      namelist/junk/a,b,c

      a=1.234
      b=5.678
      c=-123.456

      write(10,junk)

      stop
      end

The right output (which I get on my m68k-next-nextstep3 system,  
using g77-0.5.21 + gcc-2.7.2.3) is:

&JUNK
 A =  1.233999968,
 B =  5.677999973,
 C = -123.456001282/

in file `fort.10'

TIA,
Toon.
