Hello Chris,

::I tried running it in gdb myself, but did not get any useful results.
::I used your script, and this is what I got:

Oops.
Gdb on 4-STABLE does not seem to support code produced with gcc32. :-(
To further debug this problem, We must decide whether:
1) to re-compile jdk13+hotspot with system gcc(2.9.5.4) that gdb can
handle, by modifing ports/jdk13/Makefile.
or
2) to install gdb5x that can handle code from gcc32.
hope this helps,
haro
