Kai,
I'm somewhat confused now. I always thought that stdcall is a calling convention
specified in a context of MS ABI, so that "stdcall" implies "MS ABI" at least
for
the purpose of calling of the particular function with the __stdcall specifier.
It's not an area of my expertise, so I may be wr
Hi,
to report that as bug was a bit over-eager. stdcall has nothing to do
with aggregate-return-behavior.
gcc implements this already, and it is part of calling-convention.
The major issue here is that Wine uses gcc in linux-default-mode
(means sysv ABI), but of course MS-stuff expects MS-ABI her
A comment in the pointed wine patch explains the situation quite well:
MS ABI handles returning of structure so that the function gets an implicit
extra parameter: address of the memory block to be filled by the function
iplementation.
I verified with the following hack:

Hi Martin,
It's very likely that it's a problem with ABI. Wine had a problem with
this function due to incompatibility of stdcall already:

Unless stdcall is handled differently for mingw target, we need to fix
it in mingw as
"Fixed" the DemoApp.cpp by rewriting the line 216 as follows:
// D2D1_SIZE_F rtSize = m_pRenderTarget->GetSize();
D2D1_SIZE_F rtSize = { 640, 480 };
Seems that calling ID2D1RenderTarget::GetSize() is broken when
called from gcc-compiled object.
This particular method is a bit unco
