GCJ 4.03 crash on Windows 98 continued

[Jesper Juul / Soup Games]

For the record, I have gotten a bit deeper on the issue of why gcj 
4.0x executables crash on Windows 98.

The crash invitably occurs in java::lang:Class:finalize 
(natClass.cc). Below is a sample program, stack trace from gdb, and 
garbage collection log.

I am trying to look into this, but any suggestions would be appreciated.


Thanks!
