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.

  CXX      lib/ctx/lib_liblal_char_z_la-libctx.lo

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

Cheers!
