Thanks. It seems that your cache is being remapped, and the version stringview we generated by passing Ver.VerStr() to NewProvides() becomes invalid in that call. Previously, this was a string, copying the memory instead. There are potentially two ways to solve this: Allow the cache generator to remap string views where needed or revert affected parts back to strings. Obviously, strings have some performance overhead, especially on arm, which is why I replaced them with views in the first place. In the meantime, you can workaround the issue by setting APT::Cache-Start to a large value. -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/.
