Thanks for the hint! Indeed I missed the library -- libdwarf BTW -- when 
first looking for helpful code. It doesn't seem particulary popular 
(neither gcc/binutils nor gdb use it at least). It is LGPL though and still 
maintained. Will have a closer look at the API.

Yep, it is powerful. It is also ancient and "grown" code, that isn't 
particular fun to hack. Worst of all, though, the current version (6.8) 
seems to be buggy enough (under Linux at least) that using it isn't 
particular fun either. Neither the old version 6.3 Haiku currently uses, 
nor the current 6.8 can even read Haiku's gcc 2 kernel when compiled with 
debug info (the latter just hangs). All not particularly motivating to use 
it as a base for a GUI debugger at least.

CU, Ingo
