Description Daniel Vrátil 2017-02-01 20:15:54 UTC 
While editing a C++ file in KDevelop I got a crash by hitting an Q_ASSERT in Kate::TextBlock. This happens to me from time to time. The only pattern I can observe is that this happens only when I delete a small piece of code somewhere in the middle of a line, for example renaming a variable in a complex expression, but otherwise it's very random, so I can't give you exact steps to reproduce.

I'm running git master of KDE Frameworks and KDevelop.

Comment 1 Dominik Haumann 2017-02-04 23:28:18 UTC 
By default, a text buffer block initially contains 64 lines. In the backtrace, we can see that line 427 finally maps to line 62 in the requested text block. Given a default size of 64 lines, this looks feasible...

A wild guess: One possible explanation is that KDevelop somehow accesses the text buffer from different threads, and therefore messes up the text buffer. Then, things like this could happen.

Therefore: Did you have this crash also with Kate or KWrite?
