I don't believe the stack size has a direct relation to the crashes. The
error message is often different from time to time:
Another example:

  cd ../generated;   /pkgsrc/wip/jdk15/work/bin/java -classpath .
  MakeDeps
  diffs UnixPlatform platform.current includeDB.current
  /pkgsrc/wip/jdk15/work/hotspot/build/bsd/platform_i486 includeDB 
  Internal error: caught an unexpected exception.
  Please check your CLASSPATH and your installation.
  java/lang/NullPointerException
     at gnu.classpath.SystemProperties.getProperty (SystemProperties.java:123)
     at java.lang.VMClassLoader.<clinit> (VMClassLoader.java:83)
  ...

The only thing way I have found to complete a jdk build, is to recompile the
kaffe binary. This is why I think there is some sort of miscompilation /
memory corruption going on.
