This is fine, but since the segfault happened on the host side, you
could simply have built the program with debugging info ("-ggdb" in
CFLAGS, no "-s" in LDFLAGS) and run it under gdb. Then when it
segfaults, you'd be back in gdb, and you could see what source line the
crash happens on.

Did it successfully find and submit any share by now?
How long did you run it for?
Are you confident the problem is solved?
