I think this happens because reread_symbols doesn't reset
the quick_addrmap.  I am going to test this theory.

If you did not see gdb re-reading the symbols, then I don't have
a theory.  That would be useful to know.

I looked, and this bug is fixed on the archer-tromey-delayed-psymfile
branch.  However, the fix isn't in gdb-archer.patch.
Maybe this is a merge error, or maybe it is just that a new merge is needed.
Jan, let me know if there is something else I ought to do here.

It is missing in archer-jankratochvil-fedora12 as it was accidentally included as a part of the archer-tromey-delayed-symfile merge from master e421d7b026e77f4dc127de49c01e80d533eb6825.
