Something is telling porkies in that back trace.
get_alias_text() is a small routine that is only called during
some (obscure) command line edit actions.  It isn't recursive.

I'd do an 'nm -n sh' and sort out the correct symbols for the
return addresses ('objdump -d sh' might help validate them as well).
