Hello,

I am building ldc on Nix (https://nixos.org/nix/) but keep 
getting an error while running the cppa.d test from the dmd 
testsuite (https://github.com/ldc-developers/dmd-testsuite).

Apart from that all other tests pass.
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: https://github.com/ldc-developers/ldc/issues
