            Bug ID: 280256
           Summary: [GTK][WPE] IPC::Connection fails to unset FD_CLOEXEC
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WPE WebKit
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jani at igalia.com
                CC: bugs-noreply at webkitgtk.org

There's a logic error in UniStdExtrasUnix.cpp where unsetCloseOnExec(int) expects fnctl(...) F_GETFD to return -1 as a flags value before trying to remove FD_CLOEXEC flag. However, -1 indicates error so FD_CLOEXEC never gets removed and calling function in ConnectionUnix createPlatformConnection has RELEASE_ASSERT which leads to crash.
