operations remove 00 prefix from addresses which leads to crashes.

[mhhf]

I discovered this first in ethereumjs-vm 1.4 and could reproduce it in 2.0. Strangely this bug is system specific - it lead to a crash on Ubuntu but succeeded on OS X.

The error happens on a deployment of contract A which deploys another contract B. Code was compiled with solidity 0.4.3

At some Point the stack look like the following:

0 0x00b68db15676a4024a0b2cfe93c41c10c2323c44  <- B's address after deployment
1 0x01
...

Here the operation MUL is performed which produces the stack:

0 0xb68db15676a4024a0b2cfe93c41c10c2323c44
...

Note that the new address misses its 00 prefix which later leads to an error.

Can you tell what is the exact crash you see?

It is a bit messy how the stack items are handled, there was an unfinished PR to sort that out (#37).

[mhhf]

The exact crash is: Error: VM Exception while executing transaction: out of gas

However, this is because at some point: EXTCODESIZE is called on 0xb68db15676a4024a0b2cfe93c41c10c2323c44 which ultimately leads to a empty trie lookup and with this to an invalid jump

@mhhf thanks! Will check it soon.

[mhhf]

when can we expect a version bump with this?

After #84 is merged, hopefully all this week.
