I am still not able to produce a short test case, but maybe this will help:
http://git.busybox.net/busybox/tree/editors/sed.c?h=1_16_stable&id=1_16_1#n738

In the function add_input_file(), the 'file' argument is not a NULL pointer,
but at the end of the function, G.input_file_list[G.input_file_count-1]==NULL
(and !=file in particular), which ultimately leads to the segfault.
