[Bug 46380] New: user32/tests/ winstation.c leaves behind an explorer window under valgrind

Aug. 28, 2026

https://bugs.winehq.org/show_bug.cgi?id=46380 Bug ID: 46380 Summary: user32/tests/winstation.c leaves behind an explorer window under valgrind Product: Wine Version: 4.0-rc4 Hardware: x86 OS: Linux Status: NEW Keywords: download, source, testcase, valgrind Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: austinenglish(a)gmail.com Distribution: Gentoo This is likely a regression, though I haven't checked/bisected. If I do: $ cd $WINE/dlls/user32/tests/ $ make winstation.ok The tests finish (with one failure, bug 36676), and no explorer process remaining according to ps. If I instead do: $ . ~/vg-wrapper.sh $ cd $WINE $ ./wine start /min winemine $ cd $WINE/dlls/user32/tests/ $ make winstation.ok The tests again complete, but there's an orphaned explorer process that sticks around: austin 5790 15.5 1.1 2179776 186928 pts/4 Sl 22:59 0:26 valgrind /home/austin/wine-valgrind/loader/wine-preloader /home/austin/wine-valgrind/loader/wine C:\windows\system32\ex plorer.exe /desktop Which screws up my scripts, as they wait for wineserver -w to consider the tests to be done. I have to manually kill that process afterward. I'll try to see if it's a regression as time permits over next few days. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
