Comment (by anonymous):

 Two updates:

 * I'm still getting tons of UBSan unaligned access warnings also on the
 latest version of Lockfree from git with our production code, although the
 problem with the original reproducer seems to be gone... maybe worth it
 letting unit tests run through UBSan or so.

 * The segfaults that I've mentioned were unrelated to the Lockfree, just
 triggered by it, ended up being botched singletons in our code, which
 weren't single after all. The rest of the analysis is unaffected though.
