           Summary: winscard:winscard - The 32-bit test crashes in Wine
                    due to incorrect libpcsclite function signatures
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2

winscard:winscard - The 32-bit test crashes in Wine due to incorrect
libpcsclite function signatures:

winscard.c:49: Test failed: got 80100004
winscard.c:52: Test failed: got 6
winscard.c:61: Test failed: got 6
[...]
winscard.c:120: Test failed: got deadbeef
Unhandled exception: page fault on read access to 0xdeadbeef in 32-bit code
(0x6d702b0e).

See https://test.winehq.org/data/patterns.html#winscard:winscard

Where 0x80100004 == SCARD_E_INVALID_PARAMETER

The only important failure is the first one: SCARD_E_INVALID_PARAMETER.
This happens because Wine's winscard implementation passes NULL context pointer
to the libpcsclite SCardEstablishContext() function.
And this happens because that function takes a 32-bit scope value while
unixlib.c declares that parameter are 64-bit so the remaining parameters are
all shifted.

That makes the commit below the source of the bug:

winscard: Implement SCardEstablish/ReleaseContext() on top of libpcsclite.
