Comment 1 Francis Herne 2021-10-05 14:29:40 UTC

From the backtrace, this crash is actually in the Clang-based C++ parsing. The bug appears to be inside libclang rather than KDevelop as such.

You were using llvm/libclang 8 which is old and lacks many bugfixes for this sort of issue; it's quite likely this has been fixed upstream in the meantime.

Sorry for the slow triaging, KDevelop has quite a backlog of reports and few people handling them. :-(
