Hello, As my paste on irc lisp, did not have any answer, I turning again to this more specialized mailing list. I have this MClim problem. The application runs fine on Linux with SBCL 1.0.13, xorg-x11-server 1.3.0.0-9.fc7, a recent version of MClim. But doesn't on my Mac (Darwin PowerPC) with MacOS 10.5 (leopard), SBCL 1.0.16, cvs version of MClim, Xquartz 2.1.5 - (xorg-server 1.3.0-apple22)(2.1.5). I have tried to create the smallest as possible application where the problems occurs (attached). Just compile the file and launch mini::(start) On Linux, I have the desired behaviour: a circle blinks (red/green/red/...) on the display pane and at the bottom of the window application, the "quit" button is displayed and works. On the Mac, the circle blinks correctly but the "Quit" button never shows up. For a while the application is killable with C-c C-c (under Slime), but after a while there is no way to kill it than to stop Lisp and restart everything (even /the/ <http://www.lispworks.com/reference/HyperSpec/Body/s_the.htm> X server). Note that this application used to work on Mac OS 10.3 (Panther) with older versions of everything. I suspect the X server to behave differently from before. But now I don't see how to make the application work. This is too bad, as I usually use a similar application for my Lisp undergraduate course. If anyone has an idea, it will be welcomed.

[mcclim-devel] string-input-editing-stream - stream-peek-char fixup
by Mike Watters 21 Jan '09

21 Jan '09

accept-from-string was giving me program stack overflow errors on clisp (checked 2.44.1 and 2.45). I tracked it down to an infinite loop apparently caused by a stream-peek-char method on string-input-editing-stream (see attached patch).

Looks like the initialize-instance method on string-input-editing-stream was in error (see attached).
