Strange crash. Looks like this "const BacktraceLine& line" reference in gdbhighlighter.cpp line 76 is an invalid reference. Milian, can you have a look as well? indeed looking at the code I would assume the iterator accesses is unchecked and hence leads to the crash hm... that would probably mean though that the text is not in sync with the line cache... anyhow, to prevent this being more pedantic in the code should not hurt. A proper way to reproduce would be tremendous though Created attachment 104319 [details]

I'm also experiencing this on Kubuntu Zesty 17.04 Beta 1.
Indeed, this is still happening after the Qt5 port. Updated backtrace at bug 381644. *** This bug has been marked as a duplicate of bug 381644 *** |
