Ok.. I enabled debugging, I think:

D: [pulseaudio] main.c: Compilation CFLAGS:  -pipe -Os -g2
-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -Wall

-Wendif-labels -Wcast-align -Wstrict-aliasing -Wwrite-strings
-Wno-unused-parameter -ffast-math -Wp,-D_FORTIFY_SOURCE=2 -fno-common
-fdiagnostics-show-option

But I can't get gdb to work:

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

I also noticed the command line args for backtrace, but I don't get
anything more from that either:

What am I missing?

Thanks as always
