error not thrown for non-minimally encoded stack integers

[mulllhausen]

hi, just running the following script in webbtc.com/scripts and its not throwing an error when it should be:

input: ff0080
output: OP_NEGATE OP_NEGATE

the middle 0x00 is redundant, and since OP_NEGATE calls CScriptNum with fRequireMinimal the core client would throw an error here. it would be good to at least put a warning so that others will be aware that this script will not evaluate correctly in production.

also, thanks for the webbtc script tool - i have found it very useful!

cheers,
peter

Hi Peter,

good point, all the verification flags are now enabled by default and you can disable them separately. This works with an input script of 01, for example, to trigger verify_minimaldata.

But unfortunately your specific example still doesn't work, see lian/bitcoin-ruby#168.
