1. execute "java Simulator2D", Then press the "start" button
   in the window created by the application.

2. The source code is on our ftp server: ftp.neurop2.ruhr-uni-bochum.de/pub/javabug
   In the same directory is also an archive file containing all the *.java and *.class files.

3. the OS says simply "Segmentation fault (core dumped)"

4. This is the stack read from the core with gdb:
(gdb) where
#0 0xef71dd98 in markChildren ()

5. We believe that the problem with the program is the very
complex interconnection structure that is build: the
program is a simulator of neural networks, and the GC seems to
have problem when each neuron of the simulated NN
is interconnected to more that one neighbor
(variable "latl" in the user interface and in
the code).

6. What about sending us a Java T-shirt (size: large) and a
Java black cap, if this information was useful to you? :-)
