I would recommend adding the --verbose flag to see the exact commands invoked. That will print how the D compiler was invoked. The copy-paste the exact command and add the -v flag (for verbose). To the same with the C compiler and the linker.

The flag -L-lc seems to have been passed to the library.
This is the full error message after running it with dub test --verbose

You need to continue to invoke the sub commands, that is, DMD, Clang and the linker with the verbose flag (-v) added. There's no point in looking for "-lc" since the C standard library on macOS is placed in /usr/lib/libSystem.B.dylib.

I've managed to isolate and identified the problem. The problem is these two lines [1]:

pragma(mangle, "malloc") void* qualifiedMalloc(size_t size);
pragma(mangle, "free") void qualifiedFree(void* ptr);

On macOS all C symbols are mangled with an underscore prefix, meaning the "free" and "malloc" symbols are actually named _free and _malloc in the binary.

This is easy to verify by:

$ cat main.c
void foo();

int main()
{
    foo();
    return 0;
}

$ clang main.c
Undefined symbols for architecture x86_64:
  "_foo", referenced from:
      _main in main-8a6861.o

Here we can see that the linker is looking for the "_foo" symbol, while in your output it's looking for "free", without the underscore prefix.

When pragma(mangle) is used on an extern(C) symbol the compiler will automatically handle the prefixing of the symbol on macOS, making it line up with any C symbols.

Functions with D linkage have their own mangling, prefixed with _D, the fully qualified name mangled and the signature. It seems like that when using pragma(mangle) on function with D linkage the compiler will output the symbol exactly like it's specified in the source code, in pragma(mangle). This can be verified by:

$ cat main.d
void foo();

void main()
{
    foo();
}

$ dmd -c main.d
$ nm main.o | grep foo
U _D4main3fooFZv

And when using pragma(mangle):

$ cat main.d
pragma(mangle, "foo") void foo();

void main()
{
    foo();
}

$ dmd -c main.d
$ nm main.o | grep foo
U foo

No underscore prefix.

This happens to work on Linux because on Linux this mangling (with the underscore prefix) is not used for C symbols. But since the functions are not declared as extern(C) we're actually calling C functions using the D calling conventions, which just happens to work in this case because the C and D calling conventions are mostly the same.
