I know the WinIB source tree will not compile with the Vista (or later)
WDK (at least will not compile for checked 32-bit platforms). The
problem is the compiler aborts when processing __ptr64 pointers inside a
structure. The WinIB stack uses this in LOTS of places.
I'm not super optimistic about Microsoft fixing the compiler anytime
soon, because I also see compiler bugs in the code generation for
InterlockedAnd (and other Interlocked functions) that have been know for
more than a year, are not fixed. The most recent WDK betas seems to have
a fix for InterlockedAnd in the debug build, but the free build still
gets it wrong.
The following will reproduce the __ptr64 bug:
---------------------------------------------------------------
#include <ntddk.h>
struct {
void (* __ptr64 funcPtr)(long val);
} *var1;
void test(long val)
{
if (val == 0)
return;
// the following line crashes the 6000/6001 WDK 32-bit compiler
with
// error C1001: An internal error has occurred in the compiler.
var1->funcPtr(0);
}
NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING
RegistryPath)
{
var1->funcPtr = &test;
test(1);
return STATUS_SUCCESS;
}
--------------------------------------------------------------
The InterlockedAnd bug shows up in code like:
// atomic test and clear
If (InterlockedAnd(&flag, 0)) {
// this code never executes
// InterlockedAnd is documented to return the old value
// but actually returns the modified value
}
Binaries compiled using the W2k3 SP1 DDK can run on Vista, but doing
development on the latest tools is a serious problem. I view it a
Microsoft problem, since it was something in the Vista (and later) WDK
compiler that broke.

Subject: [ofw] Vista supported?
Hi,
What is the status of support for Vista? Should SRP work?
Regards,
Mirko
