solidity_tricks's Issues

c.someNum points to the address space of storage variable

The bug example in the hoisting write up is worse than your write up suggests. c.someNum will be pointing the storage variable one, meaning you could accidentally overwrite one if you were to attempt to set c.someNum to some value. To verify, call main(0) until one is equal to 10 and your proceeding calls to main will revert.
