https://bugs.winehq.org/show_bug.cgi?id=44818 Bug ID: 44818 Summary: ntdll.NtClose (kernel32.CloseHandle) should throw invalid handle exception (EXCEPTION_INVALID_HANDLE) for invalid handles when run under debugger Product: Wine Version: 3.4 Hardware: x86-64 OS: Linux Status: NEW Severity: normal Priority: P2 Component: ntdll Assignee: wine-bugs(a)winehq.org Reporter: focht(a)gmx.net Distribution: --- Hello folks, to track https://github.com/wine-staging/wine-staging/blob/master/patches/ntdll-Excep... Unfortunately there is no further information/details. My guess would be that Sebastian observed this behaviour while debugging some application under native Windows. MSDN: https://msdn.microsoft.com/en-us/library/windows/desktop/ms724211(v=vs.85).a... --- quote --- If the application is running under a debugger, the function will throw an exception if it receives either a handle value that is not valid or a pseudo-handle value. This can happen if you close a handle twice, or if you call CloseHandle on a handle returned by the FindFirstFile function instead of calling the FindClose function. --- quote --- Some forum thread: https://social.msdn.microsoft.com/Forums/vstudio/en-US/fd5deb8e-4003-4de6-94... $ wine --version wine-3.4 Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.
