APPROVE COMMIT 21.5 RECOMMEND 21.4 I decided to see if I could do something about the perennial progress bar crash. I'm unable to reproduce at the moment and haven't found a report that localizes it very well, but based on one report that has a backtrace with XFillRectangle crashing, I'm guessing that it has to do with the function GaugeMercury (which won't appear in most backtraces because it's static). The attached patch fixes a genuine bug, which has some chance of being related to the crash. All of the callers of GaugeMercury pass it ints in the val0 and val1 arguments, but they are declared Cardinal, which is X-ese for "unsigned". Having done a bunch of fontlocking with it, as least I can say it doesn't cause a new crach for me. However, I can't say for sure it will help. And as usual there's a gratuitous (but related) doc change. I never saw a docstring that didn't need fussing with. :-) Index: lisp/ChangeLog =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/lisp/ChangeLog,v retrieving revision 1.795 diff -u -r1.795 ChangeLog --- lisp/ChangeLog 12 May 2007 13:12:26 -0000 1.795 +++ lisp/ChangeLog 20 May 2007 14:32:02 -0000 ＠＠ -0,0 +1,4 ＠＠ +2007-05-20 Stephen J.
