I always got a segmentation fault with make test-all TESTS="fiddle" and --enable-bundled-libffi on macOS.

I was able to reproduce this. My guess is that the bundled libffi is failing to compile, but then the gem compiles against the bundled ffi headers, but links against the hombrew libffi. I opened a PR here to demonstrate the issue, but I'm not sure how to fix it yet.

I heard "this option for only windows environment" from @nobu (Nobuyoshi Nakada).

I'm not sure what's supported platform with this option.

@kou (Kouhei Sutou) Do you have any opinion?

[kou (Kouhei Sutou)]

It may be true because Fiddle has patches only for Windows.

I'm OK that we declares that --enable-bundled-libffi isn't supported on macOS.

@kou (Kouhei Sutou) Thanks. I submitted https://github.com/ruby/fiddle/pull/98

I created https://github.com/ruby/fiddle/pull/113. It removed --enable-bundled-libffi and add --with-libffi-source-dir. We leave from the bundled source code from Ruby 3.2.
