           Summary: ntdll/info test shows an invalid read (valgrind)
           Product: Wine
           Version: 1.3.13
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Keywords: download, source, testcase
          Severity: minor
          Priority: P2
         Component: ntdll
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: austinenglish at gmail.com


Invalid read of size 1
    at  virtual_check_buffer_for_write (virtual.c:1664)
    by  NtReadVirtualMemory (virtual.c:2778)
    by  test_readvirtualmemory (info.c:1075)
    by  func_info (info.c:1416)
    by  run_test (test.h:556)
    by  main (test.h:624)
  Address 0x1234 is not stack'd, malloc'd or (recently) free'd

Looking at the code, however, it's intended:

/* illegal local address */
status = pNtReadVirtualMemory(process, teststring, (void *)0x1234, 12,
&readcount);
ok( status == STATUS_ACCESS_VIOLATION, "Expected STATUS_ACCESS_VIOLATION, got
%08x\n", status);
ok( readcount == 0, "Expected to read 0 bytes, got %ld\n",readcount);

filing a placeholder bug.
