--- Comment #1 from dark_sylinc at yahoo dot com.ar ---
Update:

1. Confirmed to be broken with gcc 7.2
2. When I said fsanitize; I meant fsanitize=undefined
3. When code is slightly modified as in the new attachment, the crash is gone.
But it appears again if after calling a.destroy(); we add a.~FastArray();
