    ACK fabe592fd348a9961de363d5f4821505bd5dd6e3

    Maybe squash the two commits into one because the first one leaves the tree with a compiler warning which may be a problem during git bisect with -Werror. The changes are not so big or unrelated to warrant separate commits.

  7. refactor: Avoid sign-compare compiler warning in util/asmap 
    This reverts commit eac6a3080d38cfd4eb7204ecd327df213958e51a ("refactor:
Rework asmap Interpret to avoid ptrdiff_t"), because it is UB to form a
past-the-end iterator, even if it is never dereferenced.

Then fix the compiler warning in a different way:
Instead of comparing an uint32_t against a signed ptrdiff_t, just
promote both to a type that can represent both types.

Even though in this case the ptrdiff_t should never hold a negative
value, the overhead from promotion should be negligible.

    Concept ACK

    I vaguely remember we used to have a CI build that used glibc in debug mode. Don’t we have that anymore?

    The only mention of -D_GLIBCXX_DEBUG in the repo history is f3973040028d6a7335a3265fa0e13b599b2fac3d (2014).

    There has been some -D_GLIBCXX_DEBUG mentions here on GitHub in the past: see #14624 (comment) (2018) and the recent thread #21781 (review).
