python38 +optimizations compiled with `port select --set llvm mp-llvm-10` fails

[blair (Blair Zajac)]

Using this system:

macOS 10.14.6 18G4032 Xcode 10.1 10B61

and with port select --set llvm mp-llvm-10 python38 +optimizations fails to compile. However, using mp-llvm-9.0 works.

Here's where it came into LLVM (2015) <​https://reviews.llvm.org/D14558>. Why you are seeing it now is another question.

llvm-devel is out right now -- perhaps worth trying that?

[kencu (Ken)]

all I can come up with is some kind of bug in llvm-profdata that has come up since llvm-9.0 was released. There are lots of changes in the file (it's just one file) but I can't spot the error, if there is one.
