You probably need to get gdb to load the broken lib to get a reasonable
stack trace.  e.g. assuming that you've got the broken library in /broken,
something like this might work:
gdb
set solib-search-path /broken
file ls
core ls.core

Or you might need to make a whole copy of /lib and use solib-absolute-prefix.
(I haven't actually tried this on netbsd, and gdb isn't consistent across
 different OSes wrt how these settings work)
