A diff would help to make your point.
This is my attempt to break down the solidcoin changes made since the bitcoin version it was based on:
https://github.com/doublec/solidcoinThe tag 'solidcoin/v000' is the initial bitcoin release. The tags 'solidcoin/v102' is the current source available for download. There are minor differences due to whitespace changes but this shows the code changes. This might help you identify the 40-50 bug fixes that coinhunter is talking about.
