I had similar problems with the asan tests in 1.5.0 and just removed them for now.

My guess is that the problem is the missing MACOSX_RPATH because I get a warning when configuring the build:

CMake Warning (dev):
  Policy CMP0042 is not set: MACOSX_RPATH is enabled by default.  Run "cmake
  --help-policy CMP0042" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  MACOSX_RPATH is not specified for the following targets:

   ldc-jit-rt-so

Here is the error for array:

Can't reproduce the asan problems anymore, so I enabled the tests again but disabled the dynamiccompile tests for now.

The dynamiccompile shared lib probably needs the same rpath logic as ASan:

Can you open an issue about it?

Thanks,
