Cache.flush: Cannot read property 'modified' of undefined

[jesusdiazvico]

Cache.flush (invoked by runCode) throws:

/home/test/evm/node_modules/ethereumjs-vm/lib/cache.js:89
    if (it.value.modified) {
          ^

TypeError: Cannot read property 'modified' of undefined

Of course, just adding "it.value &&" as precondition in the if prevents the error, but I'm not sure if it breaks something else...

Experimented a bit with this, not really sure what to do with it. What is the functionality of the populateCache option and in what context would this be used? Am I correct that this is deactivated atm? Would be nice if anyone can drop a note.

Getting it with ganache-cli, trying to mine 500 blocks in a loop. Adding the validation above makes it run without error, but it's annoying anyway.
