21.2.31 balloon-help crash on Solaris 2.7 25 years, 1 month

Raymond Toy

Built 21.2.31 from a full tarball on Solaris 2.7 using gcc 2.7.2.x. The following recipe gives me a 100% repeatable crash when balloon-help tries to pop up its help window. xemacs -vanilla In the *scratch* buffer, evaluate the following (balloon-help-mode) Now place the mouse over one of the toolbar buttons. Instant crash. Here's the Lisp backtrace: Lisp backtrace follows: # (unwind-protect ...) # (catch #<INTERNAL OBJECT (XEmacs bug?)

Don't the standard Athena widgets implement the `backgroundPixmap' resource, which you can use to set the background image from the C code? Then Xaw-XPM allows you to set these from X resources, by name, rather than needing to support it in each application, or something. I think.

It's possible, if difficult, to make that happen with most of the controls out there. So long as they don't do /really/ nasty, non standard things with their drawing.[1] Daniel Footnotes: [1] This does involve low-level hacking in the Windows drawing code and stuff, and subclassing someone else's drawing code. Which can be... interesting. -- I was part of that strange race of people aptly described as spending their lives doing things they detest to make money they don't want to buy things they don't need to impress people they dislike. -- Emile Henry Gauvreay

This doesn't really sound user-friendly. Think about users who don't know Lisp (the vast majority) -- to them, the above docstring is Lisp-babble.

Yeah, we discussed it in Japan. Linus acted a loser because his code bogusly _depended_ on inlining, meaning that it actually broke if the functions were not inlined. We're not in the same situation here, not even in the same ballpark.
