Description:Hello,

Asterisk will crash when setting a ResponseTimeout from a macro that is called using the Dial application.  This problem may occur when using other macros and/or using the other timeout applications as well.  Though I have not tested that.

Below is the part of my dialplan which will cause the problem.

If someone would like to add this part of my dialplan to the sample extensions.conf for CVS HEAD they may.  It works pretty well for call screening.
