Subject: Turn off bytecode jumptables to avoid Bug#36447
X-Git-Tag: emacs-27.0.90~2052
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=122198d2f1aaf0b74c102874cc9b04ae4789f54f;p=emacs.git

Turn off bytecode jumptables to avoid Bug#36447

* lisp/emacs-lisp/bytecomp.el (byte-compile-cond-use-jump-table): Set
to nil.  We can turn this back on again when Bug#36447 is solved and
we handle dumped hash tables correctly.
