<emacs>/etc/DEBUG say this:

  *** Configuring Emacs for debugging
  
  It is best to configure and build Emacs with special options that will
  make the debugging easier.  Here are the configure-time options we
  recommend (they are in addition to any other options you might need,
  such as --prefix):
  
    ./configure --enable-checking='yes,glyphs' --enable-check-lisp-object-type \
      CFLAGS='-O0 -g3'
  
  The -O0 flag is important, as debugging optimized code can be hard.
  If the problem happens only with optimized code, you may need to
  enable optimizations.  If that happens, try using -Og first instead of
  -O2, as -Og disables some optimizations that make debugging some code
  exceptionally hard.

See the above mentioned file for more details.

Probably best to send to the debbugs issue tracker; using `M-x
submit-emacs-patch' might be helpful for that.
