Comment (by trustin):

 I'm using PulseAudio 0.9.10-r1 distributed with Gentoo Linux.  The
 following is the only patch applied:

 I've tried to generate the binary with debug information, but I couldn't.
 Here's the GDB output anyway:

 I'd like to run it again with debug symbols attached, but how?  What flag
 do I need to append?  I replaced -O3 with -O, removed -fomit-frame-
 pointers, added -ggdb, and removed -UNDEBUG, but it still doesn't generate
 debug binary.
