          Platform: x86

Hello,

encountered this while looking at "Dirt 3" game installer ...
The installer enumerates install languages and builds a listbox filled with
empty language strings.

For whatever reason the installer calls kernel32.GetLocaleInfoA/W with LCTYPE
0x73 which seems to be invalid (didn't find any info in MSDN/PDK)?
Wine doesn't validate these "holes" and returns success:

--- snip ---
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x73,0x32ea04,256)
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x73,0x32ea04,256) returning 1
L""
0009:trace:listbox:ListBoxWndProc_common [0x10068]: msg LB_ADDSTRING wp
00000000 lp 0032ee04
...
0009:trace:listbox:LISTBOX_InsertString [0x10068]: added item 0 L""
0009:trace:listbox:ListBoxWndProc_common [0x10068]: msg LB_SETITEMDATA wp
00000000 lp 00000409 
--- snip ---

http://source.winehq.org/git/wine.git/blob/HEAD:/include/winnls.h#l296

--- snip include/winnls.h ---
 296 #define LOCALE_IREADINGLAYOUT       0x0070
 297 #define LOCALE_INEUTRAL             0x0071
 298 #define LOCALE_INEGATIVEPERCENT     0x0074
--- snip include/winnls.h ---

If these holes are rejected (ERROR_INVALID_FLAGS), the installer gets it right
and uses a proper way of retrieving language names:

--- snip ---
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x4,0x32ea04,256)
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x4,0x32ea04,256) returning 8
L"English"
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x8,0x32ec04,256)
0009:trace:nls:GetLocaleInfoW (lcid=0x409,lctype=0x8,0x32ec04,256) returning 14
L"United States"
0009:trace:listbox:ListBoxWndProc_common [0x10068]: msg LB_ADDSTRING wp
00000000 lp 0032ee04
...
0009:trace:listbox:LISTBOX_InsertString [0x10068]: added item 0 L"English

...
--- snip ---
