Two observations using GDB 13 snapshot

Using the latest snapshot of GDB 13 (MinGW build on native Windows), I
see some strange behavior I've not seen with previous versions:

. Very long time to read symbols. E.g., reading symbols of its own
binary takes a whopping 2 minutes. GDB 12.1 does the same in
under 10 seconds.

. The (top-gdb) prompt doesn't appear when debugging GDB with
itself.

Are these bugs or features?
