Which is this in case anyone else was wondering:
'-fsanitize=address'
Enable AddressSanitizer, a fast memory error detector. Memory
access instructions will be instrumented to detect out-of-bounds
and use-after-free bugs. See
<http://code.google.com/p/address-sanitizer/> for more details.
The run-time behavior can be influenced using the 'ASAN_OPTIONS'
environment variable; see
<https://code.google.com/p/address-sanitizer/wiki/Flags#Run-time_flags>
for a list of supported options.
