I've run into this before. I'm not sure of the exact cause however it may be associated with changes made to the JDK 1.4.1-03 and up with Linux. Try either changing back to J2SDK1.4.1-02 or update your system.
I had one RH9 box that I kept up todate which is currently 2.4.20-30.9, jdk 1.4.2, and ant 1.6.1 which worked fine and then I tried setting up a second RH9 box with 2.4.20-8, jdk 1.4.2, ant 1.6.1 and the exact same build script and source code and it would fail with a signal 11 error such as you have below. I didn't have the luxury of tracking down the specific issue so I just updated the second RH9 box and everything worked fine. Good luck.
