Class layout question

Wed Jul 13 18:44:00 GMT 2005

Thanks for all the replies. I think the layout difference is a red
herring in terms of why my java programs don't run. I built HP-UX gcj
with --enable-threads=posix and Linux gcj without this option so that is
why the layout looks different. The code is probably the same because
nothing in the small program uses that field.
If anyone would like to help me with figuring out what my real problem
might be, here is what happens when I try to run a java program on IA64
HP-UX:
gcj -g x.java -mlp64 --main=x -o x
gdb x
(gdb) r
Starting program: /home/sje/java/x
Program received signal SIGSEGV, Segmentation fault
 si_code: 2 - SEGV_ACCERR - Invalid Permissions for object.
