Crash in Carbon XEmacs 21.5.26-carbon-b5

================================================================ Dear Bug Team! I am running Mac OS X 10.4.6 on a PowerPC G4. I downloaded xemacs-21.5.26.tar.gz from a standard XEmacs site, and xemacs-21.5.26-carbon-b5.diff.bz2 from Andrew Choi's Carbon XEmacs page (as linked by www.xemacs.org). I followed the build instructions in the carbon/README file with no modifications, everything went smoothly and as described. With no init file xemacs seems to come up OK and seems to behave generally as expected. However, if I create an .xemacs directory with just an init.el containing the following text: ----cut here---- (setq minibuffer-frame-plist '(top -1 left 1 height 3)) (setq initial-frame-plist '(minibuffer nil [default font] "Courier:13")) ----cut here---- and then start xemacs, I get the following behavior: An initial window comes up that looks the same as with no init file. If I type any key to this window, the app crashes, creating a window with the following information: ----cut here---- EXC_BAD_ACCESS (0x0001) KERN_INVALID_ADDRESS (0x0001) at 0x0591a010 Thread 0 Crashed: 0 vecCGSBlendXXXX8888 + 420 1 ripd_Mark + 324 2 ripl_BltImage + 908 3 ripc_RenderImage + 256 4 ripc_DrawImage + 3532 5 CGContextDelegateDrawImage + 76 6 CGContextDrawImage + 340 7 HIViewDrawCGImage + 284 8 main_view_handler + 604 (frame-carbon.c:150) 9 DispatchEventToHandlers(EventTargetRec*, OpaqueEventRef*, HandlerCallRec*) + 692 ----cut here---- (The window asks if I want to close, report, or attach debugger. I tried the debugger, but it seemed to hang, i.e., no debugger prompt for about 10 minutes.) Note I have no .emacs file. On a separate note, this Carbon XEmacs seems palpably slower than the Carbon (Gnu) Emacs package available at http://homepage.mac.com/ zenitani/emacs-e.html for almost every task. For one simple example, I can easily type ahead of Carbon XEmacs's response on my machine in just the ordinary *scratch* buffer, whereas I can only do so with great effort in Carbon Emacs. Is this speed difference to be expected? Is there any hope of XEmacs's speed being significantly improved? I like the feature set in XEmacs better (although specifiers can be byzantine) but right now the speed issue is making me stick with Carbon Emacs, since I find myself often making erroneous edits when I type ahead of Carbon XEmacs but don't realize it. Thanks for any information/advice on the topic of XEmacs's speed, I would prefer to use XEmacs but can't if the speed makes it impractical. Finally, I wasn't sure where best to send this bug. Mr. Choi's website suggests comp.emacs.xemacs, report-xemacs-bug suggests this email address. If the bug report needs to be forwarded so that it will be visible both to Mr. Choi and the main-line XEmacs maintainers, I'd appreciate your doing so.
