Slow execution (possible dos)

[namiloh]

Fuzzing found a statetest which executes rather slow on evmstate, nearly 10 seconds on 16M gas.

$ time ./evmstate  --noreturndata --nomemory --nostorage /tmp/00048858-mixed-1.json

It appears to be doing a callcode-based calltower up to around 500 deep.

It is a bit odd, actually. Sometimes it executes in three seconds, one time it took 40 seconds. Feel free to close this ticket if it doesn't reproduce, might be that my fuzzer-machine was busy doing other things.
