Any news on this one? I ran the test on 7.2 (Windows, x64, nts) and got the same error.

FAIL!

The extension did not even compile for PHP 7.3

Received this error in a production environment when parsing a particular email, however the error only triggered on auto destruction, not at parse time. As a workaround, explicitly calling mailparse_msg_free before the end of the script solved the issue.
