Title:
  gdb 7.6 can take tens of seconds to resolve symbols in C++

Status in GNU Debugger:
  Unknown
Status in “gdb” package in Ubuntu:
  New

Bug description:
  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
