Summary: incorrect calling convention used
Product: D
Version: 1.011
Platform: PC
OS/Version: Windows
Status: NEW
Keywords: wrong-code
Severity: major
Priority: P1
Component: DMD
AssignedTo: bugzilla digitalmars.com
ReportedBy: CppCoder gmail.com
the following code compiles to the asm after it. Notice that only two
parameters are pushed in the call to dllMain, when there should be three.
int main( char [][]args )
{
uint a;
uint b;
uint c;
extern (Windows) BOOL function( HMODULE hinstDLL, DWORD fdwReason,
LPVOID lpvReserved ) dllMain;
a = 1;
b = 2;
c = 3;
dllMain = cast(typeof(dllMain))(a + b);
asm { int 3; } //as a reference point
dllMain( cast(HMODULE)c, DLL_PROCESS_ATTACH, null );
return 0;
}
