fixed a bug introduced in 0.7.2 and related to the length of the variables.
If you have downloaded version 0.7.2, you MUST use this new one.
I have noticed a very small slowdown between 0.7.2a and 0.7.1 due to a different mechanism introduced for having the length of the variables.
For example 33 seconds versus 30 in deer_hunter_2005.bms.
Maybe in the next version I will try to improve it.
Anyway quickbms 0.7.1 will remain ever available so if you get strange error, try 0.7.1 too and report me the problem.
