[package] grpc/1.50.0: Build error using clang++ 19

[ormandi]

Description

I try to build the package arrow/21.0.0 with with_flight_rpc=True and with_grpc=True which depends on grpc/1.50.0 using a specific profile (please see below) both on Linux/x86_64 and macOS/aarch64 and running into the following compilation error:

/Users/rormandi/.cache/bazel-conan-home/p/b/grpc7a955a470e9ac/b/src/src/core/lib/promise/detail/basic_seq.h:499:38: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]
  499 |                     Traits::template CallSeqFactory(f_, *cur_, std::move(arg)));
      |                                      ^

I think the error is due to the more strict checks of LLVM 19 as I was able to build this with much older clang (version 14 if I'm not mistaken). But I don't have the option to use older version of clang. Also, I believe that this is more like an error in the code as it should be something like Traits::template CallSeqFactory<>(...).

If I go to the source and change it to the following I can build it successfully by manually running make:

cat ../../src/src/core/lib/promise/detail/basic_seq.h | head -n 500 | tail -n 3
          Construct(&state_,
                    Traits::template CallSeqFactory<>(f_, *cur_, std::move(arg)));
          return PollNonEmpty();

Unfortunately this does not help with the conan recipe.

I was wondering what are my options to apply the above fix to this recipe as fast as I could?

Is there a CLI or config-based attribute which I could use to specify a patch (like it is done here with these patches: https://github.com/conan-io/conan-center-index/tree/master/recipes/grpc/all/patches/v1.50.x)

By the way, I don't have the option to change the profile (mostly LLVM 19 libc++). This config is coming from our Bazel-based monorepo. The whole POC I try to do simply tries to use conan as a third party package manager for Bazel in the form of a custom module extension that runs conan with the C/C++ toolchain provided by the monorepo.

Any idea how could I fix this quickly?

Another observation. The grpc >= 1.65.0 changes the troublesome code, and indeed if I switch temporarily to the following conanfile.txt without changing the profile I can build successfully:

swig/4.0.2

I was wondering why the latest arrow depends on the fairly old (version 1.50.0) of grpc?

Could the recipe of arrow be updated to a newer version of grpc? Or using grpc/1.50.0 is strict requirement from arrow? What is the usual way to debug/resolve these sorts of problems? (Sorry if this a naive question, I'm fairly new at conan)
