Hi!
I'm not sure whether this is the appropriate place to report a bug from Apple's
linker:
$ ld -v
@(#)PROGRAM:ld PROJECT:ld64-274.2
configured to support archs: armv6 armv7 armv7s arm64 i386 x86_64 x86_64h
armv6m armv7k armv7m armv7em (tvOS)
LTO support using: LLVM version 8.0.0, (clang-800.0.42.1)
TAPI support using: Apple TAPI version 1.30
Please, don't shoot if it's the wrong place.
My project uses heavily templates, and Boost. For a long while, I was not able
to compile it with GCC on macOS because of incompatibility of the
implementation of the C++ library with which Boost.Python was compiled, but
finally, it works! Well, sort-of: it compiles, but it fails when it links
either of the three monster shared object of my project.

I'm attaching these directories. Please, let me know what else you need.
