SUMMARY
I have a Linux kernel project that used to work fine but now, partway through
scanning it I am seeing KDevelop crash. I'm seeing the following in gdb:

When I do a backtrace I get nothing but this (for thousands of iterations):

I have no idea what process is failing to start (hint, this would be useful
information).
According to dmesg I do not see any resource failures (I have several develop
sessions active with other smaller projects that are not having issues).
I am running this on a 12 core Threadripper on OpenSUSE 15.1 with the
obs://build.opensuse.org/KDE:Extra repository. Clang and all of the other tools
are installed (with their debugging information).
STEPS TO REPRODUCE
1. Open my Linux kernel session (version 5.4.x)
2. Wait for it to scan files until it hits around 15%
3. watch it crash.
