Any ideas?

It's running on Linux with gcc 6.4.0.

 It's running on Linux with gcc 6.4.0.

That module tests linking with C++ files, looks like you have 
some symbols that don't match up.  That's weird, because those 
normally work with gcc.  For each of them, use the readelf 
command from binutils to compare the symbols generated and see 
how they differ.  For example,

readelf -sW 
/tmp/nix-build-ldc-1.3.0.drv-0/build/dmd-testsuite/runnable/cppb.cpp.o |grep
foo15372

Then run the same command on the D side, ie for cppa_0.o, and 
compare the symbols.

File a bug on the ldc github if you can't figure it out:

gcc does not create the symbol at all on NixOS. I already created 
an issue for NixOS: https://github.com/NixOS/nixpkgs/issues/28896

I am not supposed to ask here but maybe someone knows about 
problems with gcc?
