[libcxx-commits] [PATCH] D75954: Cache uwnind frame headers as they are found.

[Dimitry Andric via Phabricator via libcxx-commits]

dim added a comment.

I turned on `_LIBUNWIND_DEBUG_FRAMEHEADER_CACHE`, and indeed such segfaults appear immediately after the message `libunwind: FrameHeaderCache reset`.  That means `FrameHeaderCache::MostRecentlyUsed` has just been set to `nullptr` ...
