Jeff Martin ef815f3205 Specify a concrete stack size in channel tests
The channel-stack-overflow-issue-102246 regression test fails on
platforms with a small default stack size (e.g. Fuchsia, with a default
of 256KiB). Update the test to specify an exact stack size for both the
sender and receiver operations, to ensure it is platform agnostic.

Set the stack size to less than the total allocation size of the mpsc
channel, to continue to prove that the allocation is on the heap.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
