 Yes, it does.
 
 A small correction:
 
 When I talk about CFLAGS, I mean CFLAGS and CXXFLAGS, e.g. when I include in
 both -march=prescott, seamonkey core-dumps.
 
 Note, I also deleted the .mozilla directory just to be on the save side.

 I didn't send any stack trace as I'm puzzled how to generate a usable one, e.g.
 one with symbolic names.
 
 
 For below output, I had this in mk.conf:
 
 CFLAGS=                 -O0 -g -march=prescott -pipe
 CXXFLAGS=               -O0 -g -march=prescott -pipe
 INSTALL_UNSTRIPPED=     yes
