            Bug ID: 39568
           Summary: err:dbghelp_msc:pe_load_debug_directory Got a page
                    fault while loading symbols
           Product: Wine
           Version: 1.7.53
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: dbghelp
          Assignee: wine-bugs at winehq.org

While debugging cross compiled dbus test applications I got the mentioned trace
message. 

The reason for the crash is that in module_find_cb()
... 
if ((mapping = MapViewOfFile(hMap, FILE_MAP_READ, 0, 0, 0)) != NULL)
{
     IMAGE_NT_HEADERS*   nth = RtlImageNtHeader(mapping);

     matched++;
     timestamp = nth->FileHeader.TimeDateStamp;
                 ^^^^
the return value of RtlImageNtHeader is not checked against zero, which is the
case for calling module_find_cb with non image files.

bug 38594 may have the same crash reason.
