I'm creating a [D operating system 
kernel](https://github.com/m4t3uz/leaf-d). Thread local storage 
(TLS) is not available so it cannot be used. My D kernel compiles 
correctly with DMD but it fails with runtime errors on LDC. I 
guess LDC promotes some stack variables to TLS for example:

```d
void f() {
     ubyte[15] a; // works
     ubyte[16] b; // does not work
     __gshared ubyte[16] c; // works
     MyStruct d; // does not work
}
```

How do I make LDC use the stack only? Should I file a bug report?

all on the stack.

I Need a definition of what "does not work" means i.e. with 
output of the error.

`b` is likely initialized with sse2 instructions, maybe your 
processor doesn't support sse2.

the kernel with --march=x86 --mcpu=i386 and it worked!

Thank you very much!
