Re: here strings fold newlines on MacOS
Ah, yep — sorry for the false positive. I *have* 5.1.0 installed (and bashbug
picked that up!) but the context in which I encountered the bug was indeed
Apple’s ancient version. I could’ve sworn I tested it in both, but clearly
messed that up - verified it’s fixed in 5.1.0.

This was fixed quite a while back, but still after Apple froze its version
of bash at 3.2.57. Maybe you should file a bug report with Apple.

I can reproduce the OP's result with the system bash but not with 5.1 or 5.1 patch 4. % /bin/bash --version | head -n 1 GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin18) % /bin/bash -c 'od -bc <<< $(echo -e "foo\nbar")' 000 146 157 157 040 142 141 162 012 f o o b a r \n 010 % work/destroot/opt/local/bin/bash --version | head -n 1 GNU bash, version 5.1.0(1)-release (x86_64-apple-darwin18.7.0) % work/destroot/opt/local/bin/bash -c 'od -bc <<< $(echo -e "foo\nbar")' 000 146 157 157 012 142 141 162 012 f o o \n b a r \n 010 % bash --version | head -n 1 GNU bash, version 5.1.4(1)-release (x86_64-apple-darwin18.7.0) % bash -c 'od -bc <<< $(echo -e "foo\nbar")' 000 146 157 157 012 142 141 162 012 f o o \n b a r \n 010 -- vq

Are you certain that you're not testing /bin/bash (version 3.2.57) in
the case of macOS? I ask because the bug you describe is said to have
been addressed by the release of 4.4-beta [1].
z. Bash no longer splits the expansion of here-strings, as the
documentation has always said.
You can work around it by double quoting the command substitution.
