Maximum function nesting level of ‘256’

Hi,
thank you for sharing this. I have a couple of questions to get this bug fixed:

• What image-sizes do you have registered (name and pixel-sizes please)?
• On settings screen of the plugin is a plugin-test. Please post your results.
• What′s your PHP version?
• What′s your WordPress Version?
• What′s your Crop-Thumbnails Version?

The issue was a too small function nesting level in xdebug.
The issue was fixed by increasing it to a higher number.
However, it would be a better solution if a non-recursive approach is used for that part of code because this will avoid any deep function nesting.

Thanks for responding and get in touch with the issue. Can you please provide me the image-size that caused the large recrusion.
