Fixed a variable going out of scope causing an invalid pointer access
- Follow-up to 20bdc01fa687b174a732be4483ddea4982d67ce9
- The issue was found thanks to gcc 4.7.3 on a 32 bit linux system,
where the issue became evident and caused all sorts of parsing errors
on argument-less command functions such as 'end', 'close', 'next', etc
- Special thanks to Ind for quickly pointing me to the right place!
