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

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.
