Public bug reported:
See http://sourceware.org/bugzilla/show_bug.cgi?id=15454
filed by me.
Reverting 677b1bf from the gdb git repository fixes the problem.
In this revision, gdb started searching the base classes for the symbol
too. The algorithm seems to require optimization.
Meanwhile, the problem can be worked with a one-line diff that reverts
the behavior to the pre-677b1bf. Attaching the patch
