I tried to use the 971105 snapshot of g77 on my RedHat 4.2 Linux 2.0.30 Alpha
system to compile and execute a benchmark version of one of my production 
codes. The only problem I encountered was a segmentation fault, when the
code attempted to write namelist data. When the namelist writes were removed
the code ran correctly with no flags, and with the -O2 flag. The performance
was comparable to that produced with another compiler which frontends the
machine's gcc 2.7.2.1. I was able to reproduce the namelist problem with a
short code which merely initialized 3 floating point variables and attempted to
write them as a namelist.

P.S. If this is a well-known g77 problem please forgive me. I am new to using
     g77.
