Hi,

I'm the maintainer of Protobuf and gRPC in Debian. In the process of 
updating the packages. I've a local package of Protobuf 3.28.0 RC1. Wanted 
to package gRPC 1.65.1, but it needs absl::no_destructor not yet available 
in Debian. I went back to gRPC 1.62.2 which fails to build:

First question if this Protobuf version is expected to work correctly with 
a bit older gRPC version.
Then of course, is this compilation problem of gRPC known (probably due to 
using GCC 14)? I can ask this in other group(s) if you don't relate with 
gRPC.

Thanks for any pointers,
Laszlo/GCS
