Bug #: 34810
           Summary: The winspool.drv:info test crashes on Windows 8
           Product: Wine
           Version: 1.7.5
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: spooler
        AssignedTo: wine-bugs@winehq.org
        ReportedBy: fgouget@codeweavers.com
    Classification: Unclassified
winspool.drv:info test crashes on Windows 8 as can be seen on the WineTest
site:
http://test.winehq.org/data/tests/winspool.drv:info.html
Here is a crash report:
info.c:2923: Test failed: AddJobA() failed le=50
info.c:2929: Test failed: GetJobA() failed le=87
info.c:2934: this is the last test seen before the exception
info: unhandled exception c0000005 at 0040B24A
Which corresponds to these lines:
2922 ret = AddJobA( printer, 1, (BYTE *)add_job, needed, &needed );
2923 ok( ret, "AddJobA() failed le=%d\n", GetLastError() );
 -> Failed with ERROR_NOT_SUPPORTED and no job is created.
2925 ret = GetJobA( printer, add_job->JobId, 2, NULL, 0, &needed );
2926 ok( !ret, "got %d\n", ret );
 -> Fails as expected but with ERROR_INVALID_PARAMETER, not
ERROR_INSUFFICIENT_BUFFER. So needed is 0.
2927 job_info = HeapAlloc( GetProcessHeap(), 0, needed );
 -> So here we allocate a 0-byte structure!
2928 ret = GetJobA( printer, add_job->JobId, 2, (BYTE *)job_info, needed,
&needed );
2929 ok( ret, "GetJobA() failed le=%d\n", GetLastError() );
 -> Again ERROR_INVALID_PARAMETER.
Then we crash when we try to dereference a pointer in the 0-byte job_info
structure we allocated.
So it looks like this is all because JOB_INFO_2 is not supported anymore. Yet
MSDN says nothing about that. Does that make sense?
