--- Comment #2 from Iain Buclaw <ibuclaw at gdcproject dot org> ---
Fixed the first case, and now there is a second.
Again, can't reproduce using equivalent C++ with g++. This time however I have
no idea why, as both look like they produce identical codegen on the surface.
One key difference in data types is that SArray is a built-in type S[] in D.
But otherwise ABI should be identical.
---
struct S
{
};
struct SArray
{
size_t length;
void* ptr;
};
void formattedWrite (SArray, S)
{
void (*funs)(S) = 0;
funs (S ());
}
int format (SArray fmt, S args)
{
formattedWrite (fmt, args);
return 1;
}
