Half the kingdom for a reproduction recipe that doesn't need Gnus or EBDB, or at least starts with "emacs -Q" and loads whatever packages are needed as part of the recipe. > I don't know what static compositions are, but the places where EBDB > messes with lower-level character stuff are pasted below. As you can > see it's pretty ad-hoc stuff. I don't think I see the relevance, not yet. The crash happened during routine redisplay, and ebdb-search, which is the consumer of ebdb-char-fold-table, is nowhere on the crash backtrace. So I still think a backtrace from an unoptimized build, where I can see the exact locus of the crash and ask for values of some variables, would be the fastest path to finding the culprit. Thanks.
