BLC forces normal programs to start with a closed lambda term, by mapping free variables to the divergent Omega = <code>(\x.x x)(\x.x x)</code>, the lambda calculus equivalent of an infinite loop. That makes the following 2-bit BLC program the smallest to catch fire:
<syntaxhighlight lang="c">int main(){int a=0, b=0, c=a/b;}</syntaxhighlight>▼

Other runtime errors are possible, but not as easy to use.
=={{header|Bruijn}}==
Bruijn does not have runtime errors. For debugging you can either write tests (which are run before evaluating main) or use tactical infinite loops:
<syntaxhighlight lang="bruijn">
:test ([[0]]) ([[1]])
main [[0 0] [0 0]]
</syntaxhighlight>

It's probably more effective to use <syntaxhighlight lang="j"> exit 0</syntaxhighlight> -- this approach would eliminate dependence on a variety of implementation details.

Another solution with the same number of characters (we could also use <code>mod</code> instead of <code>div</code>):
<syntaxhighlight lang="text">echo 1 div 0</syntaxhighlight>
But the shortest solution may be:
