Looks like it crashes in libLLVM. Where do you get KDevelop from and does that provider give you a choice what LLVM/Clang version to depend on?

If not, your best option would be to build your own copy of KDevelop, against an older & more stabled LLVM/Clang (which is *probably* going to be faster too, BTW). If you use the Kubuntu package for KDevelop, you can just use apt-get to retrieve the source form of that package, tweak its debian/{control,rules} files to depend on an older LLVM version and use dpkg-buildpackage to create local .deb files of which you'd have to install (with dpkg) only the one that contains the *kdevclang* binaries.

FWIW, this is one of the reasons why years ago already I argued (in vain) for a way to build just the LLVM-based parser plugin (and its dependencies) rather than having to build all of KDevelop.
