Re: 21.4.8 garbage collection crash

This Darryl> is under HP-UX 11.11i and with Motif, and so it could be a Darryl> linux or xaw3d problem. Could be. Are you a regular Gnus user? For mail? If not, I suspect that you're probably not exercising the parts of Gnus that cause us problems. Darryl> One possible issue is that, with Mule, Darryl> XRegisterIMInstantiateCallback() doesn't seem to like Darryl> being passed NULL arguments for res_name/res_class (I'm Darryl> guessing, here). The NULL pointers get passed to Darryl> _XimOpenIM(), and they get dereferenced: I've traced this under Linux (XFree86 4.1.0.1) and they don't get dereferenced for me ... uh, let me try that with an active IM ... nope, they still don't get dereferenced. In fact, on Linux _XimMakeImName doesn't seem to take res_name and res_class as arguments. Here's The Obvious Patch[tm], built with my usual options, and executed with LANG=en_US.utf-8 and XMODIFIERS unset, and executed with LANG=ja_JP.eucJP XMODIFIERS=＠im=kinput2. Seems to work fine on Linux in "exhaustive testing", about 20 sec worth. :-) I don't think I'll apply it, I offer it for testing (if you want to try). My guess is that after applying the patch, you'll get the same result. It's not the res_* things that are getting dereferenced, _XimMakeImName doesn't have a handle to them, it's something else.
