Re: [MACTCL] Getting segfault running with 8.5.2 and Mac OS X 10.5.3

[Daniel A. S. <da...@us...>]

Hi Trevor,

I cannot reproduce this crash, it looks like you may not be running  
your application on stock Tcl/Tk?

your backtrace seems to indicate that the crashing  
Tk_ResetUserInactiveTime() is called from non-standard places, in  
stock tk this is only every called from the implementation of [tk  
inactive reset] (i.e. from Tk_TkObjCmd()). Are you using this command?

the backtrace as a whole does not make a lot of sense to me, I don't  
understand e.g. why SendEventToEventTarget() should be called from  
Tk_ResetUserInactiveTime() or why DispatchEventToHandlers() would be  
calling Tk_ResetUserInactiveTime() in turn...

possibly the stacktrace is bogus due to stack corruption, you can try  
putting a breakpoint in Tk_ResetUserInactiveTime() to get a backtrace  
from immediately before the crash.

otherwise you will need to provide more detailed instructions to  
reproduce the problem and/or debug yourself any custom code and  
modifications you made to tcl/tk.
