CCLS Restart prompt after opening specific source file

[RomeuG]

Hello.

When I open a very specific file in my project, the Ccls server shuts down and there is a prompt to restart it. This is the message: Server ccls:23405 exited with status signal. Do you want to restart it? (y or n)

The file: https://github.com/RomeuG/libPkmnSave/blob/master/tests/src/main.cpp

For the software I am using:

CCLS

$ ccls --version
ccls version 0.20190823.4-6-g396d0668
clang version 9.0.0 (tags/RELEASE_900/final)

Clang

$ clang --version
clang version 9.0.0 (tags/RELEASE_900/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /bin

OS

$ uname -a
Linux xerxes 5.3.7-1-ck-haswell #1 SMP PREEMPT @1572041003 x86_64 GNU/Linux

When I open that specific file, the ccls::stderr buffer shows me this:

Process ccls stderr finished

What can I do to help you help me solve this?

Thanks.

This usually indicates that the build is at fault. There may be lots of root causes. You may follow the troubleshooting process described at https://github.com/MaskRay/emacs-ccls/issues/62

For some reason it started working. I have no clue why (no updates done).

Maybe it is because instead of opening that file directly, I opened a different project related file before opening the "offending" file.
