bug#44285: 27.1; Invalid function: make-local-variable

[noosphere@mailc.net]

I've managed to get a backtrace by breaking on "exit".  I also had to recompile Emacs with debugging symbols in order to get full debugging information (installing emacs-debuginfo was not enough).

Here's how I configured Emacs:  ./configure CFLAGS='-O0 -ggdb3 -rdynamic' --prefix=/usr/local/apps/emacs --with-x-toolkit=no --with-xpm=ifavailable --with-jpeg=ifavailable --with-gif=ifavailable --with-tiff=ifavailable --with-gnutls=ifavailable

Here is the backtrace:
