I knew for a while that dwarf output for the target is not 100% correct,
I now found one example of a wrongly generated debuginfo, could somebody
please help me and fix this problem in compiler?
I see the problem both with dwarf2 or dwarf4 debug info, with dwarf2 the
error message is a little different.
