Created attachment 246326 [details] hs_err_pid2799.log I20140819-2200 32-bit, Ubuntu 12.04 LTS, everything pretty default, Unity 2D, Ambiance theme. Got a VM crash when pressing Ctrl+S in an Untitled Text File editor. I could not reproduce. Looks similar to bug 419729 and bug 431879, but has a different "Problematic frame". # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x004ad253, pid=2799, tid=3077998272 # # JRE version: Java(TM) SE Runtime Environment (8.0_20-b26) (build 1.8.0_20-b26) # Java VM: Java HotSpot(TM) Client VM (25.20-b23 mixed mode linux-x86 ) # Problematic frame: # C [libgdk-3.so.0+0x2a253] gdk_window_get_support_multidevice+0x23 # [..] --------------- T H R E A D --------------- Current thread (0x088b3c00): JavaThread "main" [_thread_in_native, id=2799, stack(0xbf8f3000,0xbf943000)] [..] Java frames: (J=compiled Java code, j=interpreted, Vv=VM code) J 10746 org.eclipse.swt.internal.gtk.OS._gtk_widget_show(I)V (0 bytes) @ 0xb579909e [0xb5799060+0x3e] j org.eclipse.swt.internal.gtk.OS.gtk_widget_show(I)V+8 j org.eclipse.swt.widgets.Shell.setVisible(Z)V+133 j org.eclipse.swt.widgets.Shell.open()V+11 j org.eclipse.jface.window.Window.open()I+34 j org.eclipse.ui.texteditor.AbstractDecoratedTextEditor.performSaveAs(Lorg/eclipse/core/runtime/IProgressMonitor;)V+399 j org.eclipse.ui.texteditor.AbstractTextEditor.doSave(Lorg/eclipse/core/runtime/IProgressMonitor;)V+32 j org.eclipse.ui.texteditor.AbstractTextEditor$TextEditorSavable.doSave(Lorg/eclipse/core/runtime/IProgressMonitor;)V+5 j org.eclipse.ui.Saveable.doSave(Lorg/eclipse/core/runtime/IProgressMonitor;Lorg/eclipse/jface/window/IShellProvider;)Lorg/eclipse/ui/progress/IJobRunnable;+2 j org.eclipse.ui.internal.SaveableHelper.doSaveModel(Lorg/eclipse/ui/Saveable;Lorg/eclipse/core/runtime/IProgressMonitor;Lorg/eclipse/jface/window/IShellProvider;Z)V+74 j org.eclipse.ui.internal.SaveableHelper$3.run(Lorg/eclipse/core/runtime/IProgressMonitor;)V+84 j org.eclipse.ui.internal.SaveableHelper$5.run(Lorg/eclipse/core/runtime/IProgressMonitor;)V+5 j org.eclipse.jface.operation.ModalContext.runInCurrentThread(Lorg/eclipse/jface/operation/IRunnableWithProgress;Lorg/eclipse/core/runtime/IProgressMonitor;)V+6 j org.eclipse.jface.operation.ModalContext.run(Lorg/eclipse/jface/operation/IRunnableWithProgress;ZLorg/eclipse/core/runtime/IProgressMonitor;Lorg/eclipse/swt/widgets/Display;)V+48 j org.eclipse.ui.internal.WorkbenchWindow$13.run()V+25 J 94521 C1 org.eclipse.swt.custom.BusyIndicator.showWhile(Lorg/eclipse/swt/widgets/Display;Ljava/lang/Runnable;)V (258 bytes) @ 0xb5b04b50 [0xb5b049c0+0x190] j org.eclipse.ui.internal.WorkbenchWindow.run(ZZLorg/eclipse/jface/operation/IRunnableWithProgress;)V+474 [..]
There are different variants of this crash but it always happens in a call to gdk_window_get_support_multidevice. Apparently, it is fixed in Ubuntu 14.04 (GTK+ 3.10.x) as per updates on the bug 427776. *** This bug has been marked as a duplicate of bug 427776 ***
