[Mono-dev] threads.o : fatal error: error in backend: unsupported symbol modifier in relocation

[Robert N]

I am trying to compile version 3.2.0 of mono for a compliance review on OS-X (git checkout mono-3.2.0) and I'm receiving a fatal error on threads.o and domain.o during the 'make' run. Diving into libmonoruntime_la-threads.lo and/or libmonoruntime_la-domain.lo, I am getting a clang/llvm fatal error of "error in backend: unsupported symbol modifier in relocation". I've also tried checking out git tags 3.2.1, 3.2.3, etc.. and the same error occurs, Also tried x32 vs x64 builds, same error.  FYI: building the latest 4.x branches/tags work fine.

Anyone help point me in the right direction on this as I need to reproduce 3.2 builds before migrating this project code base to the 4.x line. 

Thanks in advance.
