Dose AU3_PixelSearch has bug in AutoItX 3.3.14.0?

[wangzhengbo]

I use AutoItX in java.

AU3_PixelSearch work well with AutoItX 3.3.12.0 or 3.3.10.2, but throw Invalid nemory access error with 3.3.14.0?

I write a simple java program。You can download AutoItXDemo.zip and import it into eclipse and run it.

The AutoItX contained in AutoItXDemo.zip is 3.3.12.0, and the output of the code is something like:

point.x = 0, point.y = 45

but when i use AutoItX 3.3.14.0, invalid memory access error happened.
