Thanks for the creating the great product for free!

For any user who run into the same issue, can try the following command to workaround it, it works for me at least.

rdm --completion-diagnostics=off ...

[root42]

Thank you, same problem is happening here as well. And the workaround helps, for now. But I guess there needs to be a proper fix.

[root42]

Hm, I don't get any flycheck diagnostics anymore. Is this related to the completion-diagnostics setting being off? This is a bit annoying... Did anyone ever figure out why this whole thing crashes?

[aschmitz-crnc]

@Andersbakken I had a short look but am not fluent enough in clang API, so I have no clue why the crash happens. But is there a chance this can be fixed?
Currently I am manually compiling rtags with clang-9 to still be able to use it. But it would be nice if I could switch to clang-13 eventually, as the newer clangs have better support of the more recent C++ standards.
