First of all, you are expected to build release with assertions turned off. 
So you can be sure user will not see assertion failure.

Well, you think it is better to produce incorrect result and keep working 
even if user may not notice that error?
I disagree with you completely. It is always better to crash application 
once and fix the problem rather than to have it producing incorrect results 
or showing unpredictable and/or inexplicable behavior for years.
There can be cases when human lives depend on actions of software. And if a 
process dies, you can easily detect it with a watchdog process and take 
protective measures. But if process continues functioning but does not do 
its job correctly it can be much more dangerous.
