"Recent emacs" from which branch of the repository?  Also, how recent?

(Crashes should be reported with "M-x report-emacs-bug", as there's no
doubt they are bugs of some sort, and therefore no reason to discuss
them here.  Using report-emacs-bug would have included all the
information I'm asking about above, automatically.)

The backtrace shows incorrect files and lines, and most values are
"optimized out" (and others are therefore suspect to not be the
truth).

> Any suggestions please?

Rebuild without optimizations and try reproducing the problem with
your recipe.  If successful, post the backtrace.

Thanks.
