Question regarding missing local variables in gdb

[Michael Elizabeth Chastain]

Cool, this is all the info I need.  I reproduced this on a Red Hat Linux 7
system with g++ 2.96 and gdb 5.0.

Then I did it again on a Red Hat Linux 7.1 system which has an updated
g++ (g++ 2.96-81).  The problem is fixed there.  So I recommend that
you upgrade to 7.1.

I also tested the vanilla FSF compiler, gcc 2.95.3, running on RHL 7.
The problem is fixed there as well.
