Details:

I configured with --enable-address-sanitizer-flags and then ran


./run-octave --eval "exit" |& tee leak.log


There is a leak of 8 bytes which is repeated 56 times (approximately the
number of octave value types?).  All of the leak records look about like this
one:


Direct leak of 8 byte(s) in 1 object(s) allocated from:
