CWallpaperTarget::onRepeatTimer() calls IPC::g_IPCSocket->onWallpaperChanged() without checking if g_IPCSocket is valid. When IPC is disabled (ipc=0) or not initialized, g_IPCSocket is nullptr, causing a SIGSEGV. Stack trace from coredump: #0 __normal_iterator constructor (this->m_statusObjects at 0x60) #1 IPC::CSocket::onWallpaperChanged (this=0x0) #2 CWallpaperTarget::onRepeatTimer GDB confirms this=0x0 in onWallpaperChanged, meaning g_IPCSocket.get() returned nullptr when dereferenced. Fix: add a null guard matching the pattern already used in registerOutput() and elsewhere in the codebase.
