Hi all,
</div>
<div class="default-style">
</div>
<div class="default-style">
I'm using a quite large project in kdevelop which is under constant evolution since the very old kdevelop 3.x
</div>
<div class="default-style">
I upgraded my system from 20.04 LTS to 22.04 LTS and the new kdevelop seems to crash quite quickly after having opened the project.
</div>
<div class="default-style">
It seems as if some of background parsers seem to be the troublemaker. When I disable them, I can work, but all code completion features are not operational then...
</div>
<div class="default-style">
I already reduced to to a single thread but this just extends the time before a crash.
</div>
<div class="default-style">
</div>
<div class="default-style">
Any ideas how to get deeper into this?
</div>
<div class="default-style">
</div>
<div class="default-style">
the backtrace that I can see looks always similar:
</div>
<div class="default-style">
<div class="default-style">
Application: KDevelop (kdevelop), signal: Segmentation fault
</div>
