Oh. I agree. How about - Do not use assignment in assert condition. If assignment is used, there is risk that we have disapearing bug with debug build due to side of effect of assignment. Function calls in assert condition may create this bug also when parameter or global variable is changed.
Do not use assignments in assert conditions. If you assign inside an assert condition, you risk an elusive bug that would be very difficult to spot in a debug build, due to the side of effect of the assignment. Function calls in assert conditions may also cause this problem, if they modify one of their arguments or global variables.

Thanks a lot. Much easier to understand for me too :) -- Yasuo Ohgaki
