After Updating to Xcode 11.4 I get the following error while compiling for macOS or iOS: clang: error: unknown argument: '-fcoalesce-templates'

Anyone have an idea what might be the problem?

I'm seeing that too. Looks like a compiler flag is getting set somewhere that shouldn't be. It's not being added in the script itself, and since Clang is complaining about it I'm going to assume it's coming from Boost. I'll look into it.

I found a patch on apache/kudu which fixes this issue, for boost 1.69.0. applying the patch allows me to build the framework for ios, which is what I need. building macosx is still broken, although for a different reason. https://github.com/apache/kudu/commit/e6fa761a4a60118bb61883fe8342943253f350d2#diff-d424359aa013fc54d17b0ecb4c6d52bc

Looks like https://github.com/boostorg/build/pull/560 fixes this - we'll need to update the script to conditionally apply this patch until that PR is included in a Boost release.
