I bring bad news. I am receiving seg faults and bus errors while running XOTcl code. I am running XOTcl 1.5.3 and Tcl 8.4 on both Linux x86 and OS X PPC. I received the errors randomly on both platforms. This started occuring when I reloaded the source code. At first I thought it was related to Tcl packaging, but I mostly removed calls to package require and package forget. Currently I just use source to load most files. I am writing code generation libraries and using Object eval so I may be doing new things with XOTcl. How should I go about debugging these seg faults? Are core dumps useful? I'll try to write a script that reproduces the problem, but I haven't really narrowed the problem down yet.
Any help is much appreciated.
Thanks,

Hello Ben!
I have also very seldom some segmentation faults with Tcl/XOTcl (and many another extensions). I have noticed, that it can occurs when I am debugging and changing code (by using XOTclIDE). So it is similar to your scenario. It can occurs by me when I suspend processing of one method (with tkwait - used internally by debugger) and from another event handler (beginned from Tk -command) I manipulate some objects. The program have problems when I try to fire tkwait variable (resume the debugger). So I suppose you should not reload the package by itself.
The best method to have a bug fix is to write some short script that always reproduces the error. I have not a success to write it yet. Even if I try to reproduce the same debugging session it does not occurs. Because the error is very seldom it is not possible to fix it without this script.
