The debugger can't tell you exactly what you did when you corrupt your heap, but things like this mean that's what happened. Perhaps you wrote past the end of a block you malloc()-ed, or wrote to memory you'd already freed, that kind of thing.

arm(1)							      General Commands Manual							    arm(1)

NAME

       arm - Terminal Tor status monitor

SYNOPSIS

       arm [OPTION]

DESCRIPTION

       The  anonymizing  relay	monitor (arm) is a terminal status monitor for Tor relays, intended for command-line aficionados, ssh connections,
       and anyone stuck with a tty terminal. This works much like top does for system usage, providing real time statistics for:
	 * bandwidth, cpu, and memory usage
	 * relay's current configuration
	 * logged events
	 * connection details (ip, hostname, fingerprint, and consensus data)
	 * etc

       Defaults and interface properties are configurable via a user provided configuration file (for an example see the  provided  armrc.sample).
       Releases and information are available at http://www.atagar.com/arm.

OPTIONS

       -i, --interface [ADDRESS:]PORT
	      tor control port arm should attach to (default is 127.0.0.1:9051)

       -c, --config CONFIG_PATH
	      user provided configuration file (default is ~/.arm/armrc)

       -d, --debug
	      writes all arm logs to ~/.arm/log

       -b, --blind
	      disable connection lookups (netstat, lsof, and ss), dropping the parts of the interface that rely on this information

       -e, --event EVENT_FLAGS
	      flags for tor, arm, and torctl events to be logged (default is N3)

		d DEBUG      a ADDRMAP		 k DESCCHANGED	 s STREAM
		i INFO	     f AUTHDIR_NEWDESCS  g GUARD	 r STREAM_BW
		n NOTICE     h BUILDTIMEOUT_SET  l NEWCONSENSUS  t STATUS_CLIENT
		w WARN	     b BW		 m NEWDESC	 u STATUS_GENERAL
		e ERR	     c CIRC		 p NS		 v STATUS_SERVER
			     j CLIENTS_SEEN	 q ORCONN
		  DINWE tor runlevel+		 A All Events
		  12345 arm runlevel+		 X No Events
		  67890 torctl runlevel+	 U Unknown Events

       -v, --version
	      provides version information

       -h, --help
	      provides usage information

FILES

       ~/.arm/armrc
	      Your personal arm configuration file

       /usr/share/doc/arm/armrc.sample
	      Sample armrc configuration file that documents all options
