[Swarm-Support] Access violation in WinXP

[D Joshua Chia]

I'm running Windows XP and just installed Swarm 2.1 binary and the demo
binary.

I tried running some of the demos and some of them keep crashing with
access violation.  In particular, Heatbug keep crashing by reading
address 0.  It crashes even if I build and run it from a Java IDE.  The
way I'm running Heatbug through Java is by 1) adding the swarm binary
folder to the path, 2) using share/swarm/swarm.jar in the classpath, 3)
compiling the Heatbug source code, 4) running StartHeatbugs

The output I get from the Java IDE:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x6106DDA7
Function=strncmp+0x67
Library=c:\swarm-2.1.1\bin\cygwin1.dll
