Symbol's value as variable is void: region

I'm getting this error on a variety of commands in 21.5.14, built on Mac OS X with X11 support. This has been reported recently by a few other people on other systems: -------------------------------- http://list-archive.xemacs.org/xemacs-beta/200305/msg00354.html From: "Schmitt, Christian (ext.)" <Christian.Schmitt(a)dresdner-bank.com&gt; Symbol's value as variable is void: region Hi, I (finally) came around last night and built a new binary on Windows for the latest XEmacs code from CVS. I built two versions: One with error checking and debug enabled and one without (see below). The version with debug and error checking enabled does not show the "Symbol's value as variable is void: region" error but the one without debugging enabled does. Here's a stacktrace that happens when I try to select a piece of text using SHIFT-left arrow: # bind (standard-output stack-trace-on-signal debug-on-signal stack-trace-on-error debug-on-error) # (unwind-protect ...) # bind (buffer valid start end n) zmacs-make-extent-for-region((#<marker at 424 in *scratch* 0xe69e54> . #<marker at 424 in *scratch* 0xe69e3c>)) zmacs-activate-region() # bind (buffer activate-region nomsg location) push-mark(nil nil t) -------------------------------- http://list-archive.xemacs.org/xemacs-nt/200305/msg00031.html From: Rick Rankin <rick_rankin(a)yahoo.com&gt; (Add'l info) Build problem and problem with region in 21.5 under Cygwin. Here's some additional info. I set debug-on-error to true and got the following backtrace when I tried to set the mark: Signaling: (void-variable region) zmacs-make-extent-for-region((#<marker at 1 in .emacs 0x1028cd44> . #<marker at 1 in .emacs 0x1028cd2c>)) zmacs-activate-region() push-mark(nil nil t) set-mark-command(nil) call-interactively(set-mark-command) -------------------------------- http://list-archive.xemacs.org/xemacs-nt/200305/msg00034.html From: Markus Alt <altmark(a)de.ibm.com&gt; I might also have corrupt sources, but I doubt it (as a build for Linux from the same source tree works fine). In any case I have the very same error with 21.5.13 on AIX 5.1. Here's my backtrace (similar to Rick's): Signaling: (void-variable region) zmacs-make-extent-for-region((#<marker at 387 in init.el 0x2039640c> . #<marker at 387 in init.el 0x20396424>)) zmacs-activate-region() push-mark(nil nil t) set-mark-command(nil) -------------------------------- I also tried setting debug-on-error to t and got the same backtrace as others. Can I assume this was already fixed on those other platforms, but the fix did not make it to Darwin? Can someone fill me in on the fix, so I can apply it to the Darwin version as well? By the way, this was built on Mac OS X 10.2.6, with X11 from www.osxgnu.org. I configured with --error-checking=none. The error happens when running in X11 or TTY mode.
