From: Aida Jonikienė <aidas957(a)gmail.com> Zadig passes a fixed string length to WM_GETTEXT in one place regardless of the string: https://github.com/pbatard/libwdi/blob/9b23b82a2dd1cbffc16d46c212f92c6bf8c0c... (which causes a segfault with NULL strings on Wine but not on Windows). This fixes an unrelated issue in https://bugs.winehq.org/show_bug.cgi?id=54750 (but not the main one). --- dlls/comctl32/edit.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/dlls/comctl32/edit.c b/dlls/comctl32/edit.c index 4b950412617..b7fd50a75e9 100644 --- a/dlls/comctl32/edit.c +++ b/dlls/comctl32/edit.c @@ -3183,7 +3183,7 @@ static void EDIT_WM_ContextMenu(EDITSTATE *es, INT x, INT y) */ static INT EDIT_WM_GetText(const EDITSTATE *es, INT count, LPWSTR dst) { - if (!count) + if (!count || !dst) return 0; lstrcpynW(dst, es->text, count); -- GitLab https://gitlab.winehq.org/wine/wine/-/merge_requests/6004
