Thanks for the feedback!

> Is ADDRESS_SANITIZER defined in your build?

Yes, it is configured with emacs_cv_sanitize_address=yes. Setting this
option has been done for android since emacs 25, and supposedly fixed
some malloc issue back then [1]. I tried building without setting
emacs_cv_sanitize_address=yes just now (configure then sets =no), but
it does not seem to influence this fdsan error.

I will update the issue and add the minimal non-working example
obtained here as well.
