output segmentation fault - Gpc

17 Aug 2001


      Before I spent a lot of time getting RewriteDemo to fail in the same
way, any short answer to the following?
A program that was running under Linux is failing on a sunfire cluster
with GPC recently installed.  The "RewriteDemo" in the manual executes
normally, and I've tried several variants of the following code segments
with the same results.
var dmp_file : text;
    envname  : string;  
...
    assign(dmp_file,envname+'.output');
    extend(dmp_file);
...
A gdb backtrace:
