gcc version 3.0.1 - Thread model: posix
built with ../gcc-3.0.1/configure --enable-threads=posix
on Linux Mandrake 8.0-x86


>Description:
The attached piece of code generates a segfault when compiled with gcj 3.0.1. Compiler flags used:
gcj -v --main=HelloWorld HelloWorld.java --classpath=/usr
/local/share/libgcj.jar -o Hello

Compiler output:
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/specs
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0.1/../../../libgc
j.spec
rename spec lib to liborig
rename spec startfile to startfileorig
Configured with: ../gcc-3.0.1/configure --enable-threads=posix
Thread model: posix
gcc version 3.0.1

Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
>How-To-Repeat:
Just compile HelloWorld class.

GCJ should core with:
HelloWorld.java: In class `HelloWorld':
HelloWorld.java: In method `HelloWorld.main(java.lang.String[])':
HelloWorld.java:6: Internal error: Segmentation fault
