Looks like after the IfComp node the compiler expects to fall through
to next Block and expects a CFG edge to this block. Now in my case the
next block is not necessarily the false block - so the way I am trying
to work around is by introducing a proxy false block that simply does
GoTo to the real false block.

The updated trace output his here:

The generated strlen() function worked!
