Expanding proc macros in the following codebase seem to fail with the messages:

memory allocation of 140637737325848 bytes failed
[ERROR rust_analyzer::reload] proc macro server crashed: server exited
[ERROR rust_analyzer::reload] proc macro server crashed: failed to write request: Broken pipe (os error 32)
...

Unfortunately I don't have an MRE for this.

Possible workaround could be installing ~130 TiB RAM which I haven't tried.
