Version 2.08 of LaTeX package "mfirstuc" (indirectly loaded via "glossaries-extra") is a re-implementation using modern LaTeX3 commands. Unfortunately, it is not compatible with our indexing macros and build scripts due to the use of mfirstuc's internal macros. Newer versions of mfirstuc understand an option [=v2.07] and roll back to the earlier version [1]. Therefore, as a work around, load it explicitly with that option before loading glossaries-extra. It does not affect builds on a system where an earlier version of mfirstuc is installed.

Looks like I had trespassed the mfirstuc's internal code when I tweaked the automatic capitalization of indexed terms/names. In LaTeX community, LaTeX3 provides an easier-to-program syntax for package writers and it is getting popular day by day. Most of those re-implementation have not affected perfbook, but here comes such a day. In the longer term, I might be able to come up with a better approach for future compatibility. I can't promise anything at the moment, though.
