This switches to a version of
xsnap-pub
that adds a compile-time assertion of the availability of__has_builtin()
. This function was added to gcc-10, and was missing in gcc-9. XS can produce different heap snapshots depending upon whether this function is available or not (breaking consensus, which includes the heap snapshot hashes). By mandating its presence, we ensure that all instances will behave the same way, maintaining consensus.closes #7829
