segmentation fault maybe from Tcl

[Andreas Wegerich]

Hello,

I work with swarm (2.1.1) since a few months. It works fine until our Linux 
was updated. Now there's a segmentation fault immediately after starting a 
programm (see gdb output).
The changes are:
        kernel 2.2 -> 2.4
        Tcl 8.0 -> 8.4  (maybe here's the problem)
        gcc 2.95.2 -> 2.95.3



gdb output --->

/home/rd1/m18s3/daten/test/swarmapps-2.1.1/heatbugs/.libs/heatbugs
