 * SIGABRT is not a monitored signal for Android OS, since it produces lots of useless
 * crashes due to way Android process termination hacks work. As a result the sanitizer's
 * 'abort_on_error' flag cannot be utilized since it invokes abort() internally. In order
 * to not lose crashes a custom exitcode is registered and monitored. Since exitcode is a
 * global flag, it's assumed that target is compiled with only one sanitizer enabled at a
 * time.
