As you've discovered, there have been a number of very similar bugs that 
all involving corrupted FP and threads.  It was thought that fixes for 
all such bugs were incorporated into both 5.2.* 
(http://sources.redhat.com/gdb/download/) and the mainline 
(http://sources.redhat.com/gdb/current/).

Can you please check that your problem does occur in the latest 
release/mainline, and if it does, create a bug report using 
http://sources.redhat.com/gdb/bugs/.

enjoy,
Andrew
