Fatal Exception: Crash on iPhone 5 c

[jasonvattenx]

On an iPhone 5 c, on page load, the app crashes. The error is in FSCalendarExtensions.m in line 195: PARAM_BASIC_TYPES(char, charValue).

If I comment out that line, it does not crash. I only see this on an iPhone 5 C device, have tested it on other devices, and it does not happen in simulator for the other iPhone 5 versions.

Is there a stack trace for this?

Extra info - the Fatal Exception happened in an older version of iOS also. To test out, the device was upgraded to iOS10. Error happened in both the older iOS version and now iOS10.

[WenchaoD]

The function wouldn't get called in older version than iOS10. Please test the fix in this branch.

[jasonvattenx]

Cool.

Tested, verified, fix works on an iPhone 5 c device.

Thanks a lot! When the app goes live I will send a screen shot - your library is amazing!

Thanks @jasonvattenx
