The typical combination of "-O2 -g" works pretty well, but the whole
problem is not well understood (e.g.: would a gdb update help?). The
-O0 -g case is stupid, but an issue for gcc upstream.

Instead of compiling local parts of the tree with DBG=-g I swichted
to doing the full build with MKDEBUG=yes MKDEBUGLIB=yes, wich is a
great improvement overall (and I always have debug info available quickly
when some issue comes up).
