Thanks for fixing this in various branches.

FWIW, I have been running a test box with 14.1-stable with a variant of this
patch applied for about a month and have done a few simple tests like building
test programs of a few related bug reports with -fsanitize=address. I also
built and ran tests for several LibreSSL versions and all things work as
expected. This is only light testing, but I encourage you to land this if at
all possible. I think it can only improve things.

The bug has very confusing side effects, is quite annoying and it breaks tons
of serious usage of ASAN with OpenSSL in play.
