I'm not sure what you mean.  An assertion violation on Windows calls a
function that displays an abort dialogue, giving the user a chance to
attach a debugger.  If the user does attach a debugger, she can then
display a backtrace from the debugger.  There's no other facility to
display a backtrace on Windows that I'm aware of.
