I now have a stacktrace from someone on this issue from gdb:
They used the following configuration parameters to build arm-linux-gcc cross
compilers:

The following was tested with gcc-3.4.3 and gcc-4.0.1 sources with the same issue.
===code==================================================================
$ arm-linux-gcj -v
Configured with: ../gcc-3.4.3/configure --target=arm-linux
--prefix=/group/teaching/iar/armcore-gx/toolchain
--enable-languages=c,c++,objc,java --disable-nls --nfp --with-cpu=xscale
--with-softfloat-support=internal
Thread model: posix
gcc version 3.4.3
=========================================================================

Here is the stacktrace:

===code==================================================================
$ arm-linux-gcj -ggdb --main=HelloWorld -o hello HelloWorld.java
running ./hello causes segfault

$ gdb hello
Program received signal SIGSEGV, Segmentation fault.
