Hi,

Thanks for investigating further.

I can reproduce this.  I've changed the summary to describe the issue better.

It's not necessary to build in the Eclipse IDE to experience this:

$ ecj main/Rucksack.java 
$ java main.Rucksack
Segmentation fault (core dumped)

Using:

$ ecj -version
Eclipse Java Compiler 0.894_R34x, 3.4.2 release, Copyright IBM Corp 2000, 2008.
All rights reserved.

(and same icedtea version as earlier comment)

I also tried a simple Hello World program, this did not segfault however.

Niklas, could you (or do you mind if I) upload the source to your program as an
attachment here, just in case any other URL's go stale?

Also, just to clarify when you say it crashes on some runs and not on others. 
Do you mean that with the same compiled classfile, you have run it repeatedly
using icedtea, and sometimes you get a segfault but sometimes not?  Because
this is something I have not reproduced on this end.  (or is it that this
"sometimes" behavior is regarding the OOM heap errors?)
