#9217 closed defect (fixed)

program_opencl fails if the source code was larger than 64kB

Description

Summary of the bug:

​https://github.com/FFmpeg/FFmpeg/blob/master/libavfilter/opencl.c#L254

Here, the maximum number of "rb" is "len - pos - 1", and "pos" is "len - 1" at line 260. Therefore, the condition is always true and the rest of the code would not be read.

How to reproduce:

Write any OpenCL program source file with leading 64kB white spaces, then run program_opencl filter.
