Something gets stuck on "Parsing is_mem_fun_pointer_impl.hpp (LL)..."

Thank you for the bug report

• [X] I am using the latest version of lsp-mode related packages.
• [X] I checked FAQ and Troubleshooting sections
• [X] You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

This does not appear to happen after M-x lsp-start-plain, but I don't know what that means in terms of what's at fault/how to find/fix the problem.

Bug description

I'm having problems with lsp-mode hanging when editing C++ files. At the moment it seems to consistently get stuck on the message in the title, so I'm hoping that'll provide some insight - a copy of that file on my machine is attached, it's from boost 1.83.0-5.fc40 on a fedora system, except GitHub doesn't accept *.hpp as an attachment, so I've made it into one bit block in a markdown file.

is_mem_fun_pointer_impl.hpp.md

Steps to reproduce

Have boost installed on Fedora 40, be editing C++ that eventually #includes .

Expected behavior

Not hanging forever.

Which Language Server did you use?

clangd (default installed when lsp asks me)

OS

Linux

Error callstack

No response

Anything else?

No response

Closed as after trying some random things, it looks like it's a semanticdb problem (or at least only occurs when semanticdb is on, and I'm happy to try turning it off for a bit).
