Summary: Crash when using TTM_GETTEXT + LPSTR_CALLBACK
Product: Wine
Version: unspecified
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: comdlg32
AssignedTo: wine-bugs at winehq.org

Test application: Pressing the button crashes the program under Wine (the text
shows correctly if you go over the button). Source included.
Any program crashes when the message TTM_GETTEXT is sent to a ToolTip that has
lpszText set to LPSTR_CALLBACK.
The problem seems to be in dlls/comctl32/tooltips.c, in the functions
TOOLTIPS_GetTextA and TOOLTIPS_GetTextW.
The crash happens when Wine tries to copy lpszText, which is 0xFFFFFFFF.
Test application included.
