Built GDB 20020828 snapshot (current tree) for target i586-pc-msdosdjgpp. 
Got following problem. If  the sources are compiled using option
-gdwarf-23 then GDB gets internal error (see below). It doesn't happen
if -gdwarf-22 is being used. 

It is not the first time I see this problem with current GDB tree in some last
months.

I used gcc-3.2 and binutils-2.13
