Fix issue 7995: D runtime initialization from C fails on OSX in 2.059, w...

...orked in 2.058.

I also refactored the startup code to remove duplicated code.
This will hopefully reduce this kind of bugs in the future.

I had to remove the call to "runModuleUnitTests" in "rt_init". Meaning the unit tests won't be run if the runtime is just initialized via "rt_init". This basically only happens if you start the D runtime from a C application. The unit tests are still run, just as before, for all D applications with a D main function. Don't know if this is a problem or not.

Fails this test. Reverted.

// 2311

import std.stdio;

struct X()
{
static this()
{
printf("this()\n");
}
static ~this()
{
printf("~this()\n");
assert (false);
}
}

static ~this()
{
printf("g: ~this()\n");
}

int main() { alias X!() x; return 0; }

What is the expected behavior? I get the same result with my pull request as with the 2.059 release.

You're really not making it easy for me to figure out what went wrong. I need to know:

• What exactly isn't working
• On what platforms
• What is the expected behavior

The above code snippet has the same behavior for me with my pull request applied as with the 2.059 release.

The exit status of the program must be non-zero. It was zero. Sorry for not making that clear earlier. I tested it on OSX.
