http://bugs.winehq.org/show_bug.cgi?id=29139

             Bug #: 29139
           Summary: ExtTextOutW doesn't handle failed buffer allocations
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdi32
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: disposable593-wine(a)yahoo.com
    Classification: Unclassified


In font.c (http://source.winehq.org/source/dlls/gdi32/font.c#L1847):

The central text output function ExtTextOutW never checks for NULL return
values in buffer allocations (HeapAlloc(...)). The same seems to be the case
for several other functions in font.c (see, for example,
GetOutlineTextMetricsA).
