New issue 1480 by mevi...@gmail.com: opencl runtime malloc error
https://code.google.com/p/tesseract-ocr/issues/detail?id=1480

What steps will reproduce the problem?
1. tesseract 3.04-rc1 with opencl
2. on Macbookpror
3.

What is the expected output? What do you see instead?

I got it compiled and spanish training set, and when executing:

Tesseract Open Source OCR Engine v3.04.00 with Leptonica
[DS] Profile file not available (tesseract_opencl_profile_devices.dat);
performing profiling.
