Comment (by Hello71):

 I have pushed to https://cgit.alxu.ca/tor.git/log/?h=meson an
 implementation of the shared library approach (along with a bunch of other
 crap that I'll have to separate out). This approach seems to be the most
 reliable and, with `-static-libasan`, hopefully fixes all issues with asan
 incompatibilities. remaining problems:

 1. still need to actually build a shared library, so either #23846 or
 switch to a better build system.

 2. rustdoc doesn't take `-Z sanitizer` (https://github.com/rust-
 lang/rust/issues/43031), but I think maybe we can hack around that by
 cleaning first and just accept that doctests won't have sanitizers for
 now.
