[Gm2] ulm 64bit crash

[John B Wallace Jr]

There is still a problem using the ulm libraries with the 64bit version of 
SUSE 9.3 on an Athlon 64. HelloWorld still crashes with a segmentation fault 
during execution. HelloWorld builds and executes without errors under the 
32bit version of SUSE 9.3. 


MODULE HelloWorld;

   FROM InOut IMPORT WriteString, WriteLn;

BEGIN
   WriteString("Hello World!"); WriteLn;
END HelloWorld.

Segmentation fault


Here is the output from gdb for the 64bit version:

(gdb) 


The problem seems to be associated with the SysTermIO module. If a modified 
module using a libc call for Isatty is substituted, HelloWorld builds and 
executes without errors in 64bit.
      
The CVS sources for gm2 are dated 08 January 2006 and were attached to 
gcc-3.3.6 and build (using harness-0.6) with the default compiler for SUSE 
9.3 (gcc-3.3.5).


Also, the test suite hangs up on 32bit/SUSE 9.3 builds of recent gm2 CVS 
sources (using harness-0.6):
