Segmentation fault running with Ghdl

I’m a newbie with cocotb: I’m running on Windows 64 with Anaconda Python 3.7 and ghdl. Following the install instructions I’ve done a conda install -c msys2 m2-base m2-make and pip install cocotb. (I don’t know if relevant, but the pip install failed at first complaining the install required MS Visual C++ Build Tools. Once I’d installed these, the pip install succeeded).

I’m now trying to run the basic adder.vhdl example from the cocotb documentation In a conda shell I’m doing (py37) C:\Users\DD\Documents\adder\tests>make SIM=ghdl TOPLEVEL_LANG=vhdl

but getting a Segmentation Error :

Just an update: Whilst I haven’t found a solution for ghdl in ‘pure’ Windows, by installing MSYS cocotb and the MSYS Ghdl package from here : https://packages.msys2.org/package/mingw-w64-x86_64-ghdl I am now up and running. So at at least provides a solution for us VHDL/Windows-PC users.
