kdevelop crashes if you close splitview in a specific order. steps to recreate: 1. open a file 2. splitview the file 3. close the original (left or top) 4. close the split view. crashes 100% of the time.
only crashes if the splitview is the only thing open when it closes.
Can you supply a backtrace please? I just followed your steps and it does not crash for me. Maybe it was fixed with 5.1.1? Can you try an updated kdevelop build from https://www.kdevelop.org/download please? thanks
it still crashes in 5.1.1. I'm currently building from master atm. Is there any way to actually get the backtrace from the appimage? i run it through gdb but whenever it crashes it just says no backtrace.
try attaching to the kdevelop process with gdb after launching it through appimage, does this work?
nope, just says it cant access the memory for the backtrace.
is there a way for you guys to build a debug version of the appimage? that might help out a lot. I cant build the master atm. my two versions of qt are incompatible. the version of qt that is in the 16.04 repo is too low for QProcess::errorOccurred. the version i develop with is to new and doesnt have QtWebkit.
try the nightly build: http://kfunk.ddns.net:8080/job/kdevelop-appimage-centos/lastSuccessfulBuild/artifact/KDevelop-git-x86_64.AppImage launch it normally, then attach GDB, then reproduce the crash and get us a backtrace (thread apply all bt)

is it thread 1 that crashed? gdb should tell you that on the segfault. I wonder, b/c the function you point to does not contain a dynamic_cast, so i really wonder what is going on there... I also wonder why I cannot reproduce this locally... Maybe it relates to the source formatter. What kind of file do you open? I.e. what mimetype does it have? Do you have any special source code formatter settings?
Yes, thread 1 is the one that crashed. it doesn't matter which filetype i open. i have tried .c, .cpp, cmakelists.txt, .gitignore, .csv. i dont really have any special formatter settings, especially not for txt and csv files. Thread 1 "kdevelop" received signal SIGSEGV, Segmentation fault.

Hm ok DocumentController::activeDocument actually contains a dynamic_cast, but I wonder how that can crash here. I think we'll need to valgrind this - which is probably not possible with the AppImage. Someone will have to be able to reproduce this without the AppImage and then launch kdevelop through valgrind (or compile the code with ASAN) and see why the dynamic cast breaks apart. Just by looking at the code, I don't see how this can fail here...
changing status
yea, i cant run valgrind on the appimage. luckily this is a crash that is totally avoidable.
Thank you for the crash report. As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
