`OrderedCollections` module fails to build with Bazel

[chizcake]

Information

• Package version: 1.0.0
• Platform version: macOS 12.1 (21C52)
• Swift version: Apple Swift version 5.5.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)

Checklist

• [ ] If possible, I've reproduced the issue using the main branch of this package.
• [x] I've searched for existing GitHub issues.

Steps to Reproduce

I'm using Bazel build system and I met a build failure with the following stack trace whenever I tried to use xcconfig which had -assert-config Debug flag:

INFO: From Compiling Swift module OrderedCollections:
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the project and the crash backtrace.

Surprisingly, swiftc frontend does not complain if I don't use -assert-config Debug flag. It seems like there's something wrong with _UsafeBitset.Word.next() and I tweaked it a little so that I could make it built even with -assert-config Debug flag:

I don't know why my tweak works though.. 🤔

Expected behavior

OrderedCollections module could be built.

Actual behavior

OrderedCollections module could not be built.

Bazel is not a supported build system for this package.

That said, this is very likely a real issue in the compiler, and it would be useful if we could diagnose it!

So far I haven't seen this compiler crash triggering with our supported build systems (SPM, Xcode's Swift package support and CMake), so I expect this is something specific to how Bazel invokes swiftc. Can you please provide detailed reproduction steps? (Preferably a failing compiler invocation that we can run on a freshly cloned copy of this repo, or at the very least, the full details on how you build this code with Bazel.)

(Adding the -assert-config Debug frontend option alone sadly isn't enough to trigger this.)

[chizcake]

@lorentey Thanks for the feedback! I'll add another comment after I could make a reproducible sample with Bazel.

[lorentey]

Closing due to current lack of actionable work. Please reopen with a reproducer if this continues to be a problem.
