[Bug 53795] New: Emojis crash Naver LINE (and possibly all Qt applications)
https://bugs.winehq.org/show_bug.cgi?id=53795 Bug ID: 53795 Summary: Emojis crash Naver LINE (and possibly all Qt applications) Product: Wine Version: 7.19 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdi32 Assignee: wine-bugs(a)winehq.org Reporter: pq2sx44teeigl7za(a)chyen.cc Distribution: --- Created attachment 73289 --> https://bugs.winehq.org/attachment.cgi?id=73289 Source of a trivial Qt application to reproduce the issue Naver LINE (installer at [1]) crashes if I paste some kinds of emojis, like ???? (U+1F972) or ???? (U+1F970). Crashes happen with all kinds of text boxes, including username in the login dialog, search box and messaging dialog. Crash does not happen if I uninstalled the Noto Color Emoji font [2]. Without WINEDEBUG, crashes are intermittent. With WINEDEBUG=+font, I always get crashes. The issue can be reproduced with a trivial Qt application (source attached). The backtrace from a Qt 5.12.12 MinGW debug build [3] is also attached.
From the backtrace, Qt crashes when trying to get the string from otm->otmpFullName [4]. In a gdb session, the address (otm + otm->otmpFullName) points to an invalid address (needs to add otm per [5]). Apparently GetOutlineTextMetrics does not correctly assign that pointer.
