Sure. And I told you it happens in 7-zip. Crash actually happens in your code,
that is why I fixed it there and not somewhere
dlls/hhctrl.ocx/chm.c,LoadWinTypeFromCHM(). Point is, I don't get why there is
GetChmString(info->pCHMInfo, (DWORD_PTR)info->WinType.pszCaption) called from
LoadWinTypeFromCHM when GetChmString accepts DWORD as second argument, not
DWORD_PTR... and then, why there is (offset >> BLOCK_BITS) shift in
GetChmString when offset is truncated pointer (?)
