Sorry that I forgot to add the version I was using. Just my lazyness.

I was trying the original 2.21 release which segfaulted.

Now i've tried the latest snapshot (2.21.53) which seems not being
affected by this problem. I've diffed the sources and saw that much of
the disassembling code (especially the functions calling
get_map_sym_type()) has been re-arranged, probably fixing this problem.

I will see if I can provide a reliable way to reproduce it, as it seems
to depend on the library I dump. Maybe I can build a simple C File that
produces and object containing this type of debugging symbol that fails.

I will see what I can provide, when I am back at work.
