    Looks like it crashes in libLLVM. Where do you get KDevelop from and do=
es 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, a=
gainst an older &amp; 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 deb=
ian/{control,rules} files to depend on an older LLVM version and use dpkg-b=
uildpackage 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 vai=
n) for a way to build just the LLVM-based parser plugin (and its dependenci=
es) rather than having to build all of KDevelop.
