# Run the patched latd with the malformed-RUN probe armed.

#   LATD_FUZZ=<claimed-slots> ./run_latd_fuzz.sh [normal latd args]
#
# On the FIRST circuit-timer tick of a live circuit, latd emits one RUN
# message that claims <claimed-slots> slots while carrying a single 4-byte
# slot.  The VT1200's demultiplexer walks nbr_slots with no length bound, so
# it walks off the end of the received buffer.
#
# Typical:
#   LATD_FUZZ=255 ./run_latd_fuzz.sh -d -v -ienp197s0f3u1 -sVT1200 -lestderr
