Segmentation fault on running heatbugs example program of 960513 version

[Frank Lin]

Hi,
   I got the Swarm-960513 intalled after upgrading the supporting software, 
such as BLT2.1, and libtclobjc-1.1b3. It was compiled successfully.  However, 
in testing applications, I found heatbugs got "segmentation fault" error, and 
the program was quitted.  The rest of application programs are running fine, 
except the "market" program had no ActiveGraph display while it had on the 
previous release.

   Is anyone getting the same problem?  BTW, I am runnig on the SunOS 4.1.3.

Thanks 

Frank Lin
