[Bug 1178539] Re: gdb 7.6 can take tens of seconds to resolve symbols in C++

[Alistair Lowe]

Hi guys,

Any word on when this fix will hit proposed/updates or a package will be
up for download? I've just run into this bug on a C++ project in QT5 and
it's a complete show-stopper.

Cheers

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

Status in GNU Debugger:
  Confirmed
Status in “gdb” package in Ubuntu:
  Triaged

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

  
  lsb_release -rd
