Print stack trace hangs in GCJ 3.3 branch

[Tobias Downer <toby at mckoi dot com>]

This is the first time I've compiled GCC/GCJ so if I've done something 
stupid be kind to me :-)

Compiling GCC/GCJ went fine.  Compiling and running a 'Hello World' Java 
program is fine.  The problem is I made a simple test case that prints a 
stack trace and it pauses for about 10 seconds and then seg faults.

I've attached a capture of my test.  I searched the mailing list and 
found a report that was strikingly similar to my problem (14th March);

  http://gcc.gnu.org/ml/java/2003-03/msg00231.html

And following the trail the problem appears to have been patched on 31st 
March;

  http://gcc.gnu.org/ml/java/2003-03/msg00409.html

Is this a regression of the alignment problem or has it not been 
entirely fixed yet or perhaps something else?

Toby.
