No.  If enabling the DWARF-2 CFI support causes things to break, then
you need to inspect your CFI; it is probably broken.  You need to do
prologue analysis if there's anything without CFI that you need to
handle, which there usually is - for instance PLT stubs.

Ah, now I see. The things that broke without any prologue scanning were indeed things like 'next' over library calls (PLT stubs) and things related to call dummys (callfuncs.exp).
