Not stripping the binary, I'd say.
However, that may not now be necessary. I've managed to convince myself
that the fault occurs somewhere in info/nodes.c:info_node_of_file_buffer_tags()
--- more precisely in the (inlined) call to adjust_nodestart(). The pointer
that causes the segfault when dereferenced is node_body.buffer[0]. A comparison
of the source code:
if (node_body.buffer[0] != INFO_COOKIE && min > 2)
node_body.buffer -= 3;
with the disassembly I posted earlier should convince anyone. Note the
#define INFO_COOKIE '\037'
in info/nodes.h.
