Mingw-w64 runtime failure when using clang 7.0 on Windows targeting mingw-w64/gcc

In testing the Boost Parameter library using clang-7.0 32-bit targeting mingw-w64/gcc on Windows I ran into a mingw-w64 runtime failure when attempting to run the final command-line executable program. The full message is:

Mingw-w64 runtime failure:
   Unknown pseudo relocation protocol version 65536.

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

Using clang-6.0 32-bit targeting mingw-w64/gcc on Windows the command-line executable program runs correctly. Using mingw-w64/gcc-8.1, which is the backend I am using with clang-7.0, on Windows the command-line program runs correctly. Nor does it matter what mingw-w64/gcc version I use as the backend for clang-7.0 the runtime failure persists.

There is a bug report at https://sourceforge.net/p/mingw-w64/bugs/769/, which points to a bug report at
https://sourceware.org/bugzilla/show_bug.cgi?id=23872, with a fix at
which it was suggested to me on the mingw-w64 mailing list might fix the problem I encountered. However after I applied the "fix" to the various linker scripts of the mingw-w64/gcc backend I am using with clang-7.0 the runtime failure still persisted.

I can give detailed instructions for duplicating this problem using the latest Boost 1.68 version, the source code, and the command-lines to build the executable which fails. But before I go to that length in this message I wanted first to ask if this problem has been encountered already among clang developers or via bug reports, and is therefore a known issue with clang-7.0 on Windows targeting mingw-w64/gcc ?

I have created a bug report for this clang-7.0 problem at https://bugs.llvm.org/show_bug.cgi?id=39754.
