https://bugs.winehq.org/show_bug.cgi?id=53587 Bug ID: 53587 Summary: comctl32 GetWindowSubclass crash in Notepad++ (v8.4.3 and 8.4.4 only) Product: Wine Version: 7.13 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: comctl32 Assignee: wine-bugs(a)winehq.org Reporter: xm1(a)email.cz Distribution: --- Created attachment 72970 --> https://bugs.winehq.org/attachment.cgi?id=72970 debugger screenshot right before the access violation The N++ application crashes when uses subclassing of some common controls (ListBox or EditControl) unless you use native Windows comctl32 (winetricks used successfully on x86 N++ versions 8.4.3 and 8.4.4). There has been submitted a N++ commit, which detects running under the Wine environment and disables the relevant subclassing stuff in such case, so the N++ crash will be fixed but this only hide the Wine comctl32 problem: https://github.com/notepad-plus-plus/notepad-plus-plus/commit/f2c4ecd7e1bfd5... The original N++ bug-report: https://github.com/notepad-plus-plus/notepad-plus-plus/issues/11941 N++ x86 portable releases used for testing (x64 crashes too, but I could not use the winetricks for the comparison there...): https://github.com/notepad-plus-plus/notepad-plus-plus/releases/download/v8.... https://github.com/notepad-plus-plus/notepad-plus-plus/releases/download/v8.... Earlier N++ versions (v8.4.2-) do not crash as the relevant commit for custom ctrl border subclassing has been introduced in v8.4.3. My Linux testing environment (both with the same result): - openSUSE Tumbleweed (Snapshot20220729) x64, Wine 7.13 - openSUSE Leap 15.3 x64, Wine 6 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
