[clangd-dev] Flag constant-string-class in clangd

[Andreas Ostermeyer via clangd-dev]

Hi Alex,

thanks for rapid responding.

No, compilers (both clang and gcc) work like expected. It’s only clangd that simply ignores the constant-string-class flag (neither in compile_commands.json nor in compile_flags.txt).

Cheers,

Andreas
