I had tried to fix it like this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236193

but it doesnot work. it has the same error.

save issue , looks like clang version not compatible lambda code
my clang version is
Apple clang version 11.0.3 (clang-1103.0.32.62)
Target: x86_64-apple-darwin19.5.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

it‘s a bug in llvm4.0. I had sloved it from llvm source code. https://reviews.llvm.org/rL291939, this patch fixed the bug.
