Yes, I saw some of these threads, but nothing seemed to shed light on fixes
for the scoping of this.  It is good to know Ada does this as well so that
maybe us Ada/Pascal people can get together and come up with a fix.

I submitted code that demonstrates this with my bug report as well....

The thread 
http://sources.redhat.com/ml/gdb-patches/2001-07/msg00714.html is 
probably relevant.

Following on Joel's strategy (Ada) the first thing needed is probably a 
testcase so that people know the status of the underlying code
