Uninitialized string offset: 0 (function diff_cleanupSemanticLossless)

Opened this issue · 0 comments

Sometimes, an error message appears "uninitialized string offset: 0" generated 
from line 800 "while (isset ($ equality2 [0]) && $ edit [0] === $ equality2 
[0])" in "diff_cleanupSemanticLossless". I do not know why, sometimes it works, 
sometimes not. Can you help me?

What steps will reproduce the problem?
I dont know, sometimes it appears, sometimes not...
