Thanks for the creating the great product for free!

zhihuiFan commented 2 years ago

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 commented 2 years ago

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 commented 2 years ago

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 commented 1 year ago

@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.
