Bastien Nocera e37c462f87 gtk: Fix double-free when OpenGL can't be initialised ... gtk_gl_area_get_error() doesn't return a copy of the error, but just the error. If initialising OpenGL fails, then GtkGstGLWidget will consume the error, and cause GTK to try and display freed memory. ==50914== Invalid read of size 8 ==50914== at 0x4C4CB8A: gtk_gl_area_draw_error_screen (gtkglarea.c:663) ==50914== by 0x4C4CB8A: gtk_gl_area_draw (gtkglarea.c:687) ==50914== by 0x4E061CA: gtk_widget_draw_internal (gtkwidget.c:7084) ==50914== by 0x4BAEFB1: gtk_container_propagate_draw (gtkcontainer.c:3854) ==50914== by 0x4D4B6BF: gtk_stack_render (gtkstack.c:2207) ==50914== by 0x4BB4B03: gtk_css_custom_gadget_draw (gtkcsscustomgadget.c:159) ==50914== by 0x4BBA4C4: gtk_css_gadget_draw (gtkcssgadget.c:885) ==50914== by 0x4D4D780: gtk_stack_draw (gtkstack.c:2119) ==50914== by 0x4E061CA: gtk_widget_draw_internal (gtkwidget.c:7084) ==50914== by 0x4BAEFB1: gtk_container_propagate_draw (gtkcontainer.c:3854) ==50914== by 0x4BAF0C3: gtk_container_draw (gtkcontainer.c:3674) ==50914== by 0x4E061CA: gtk_widget_draw_internal (gtkwidget.c:7084) ==50914== by 0x4BAEFB1: gtk_container_propagate_draw (gtkcontainer.c:3854) ==50914== Address 0x187a0818 is 8 bytes inside a block of size 16 free'd ==50914== at 0x48480E4: free (vg_replace_malloc.c:872) ==50914== by 0x49A5B8C: g_free (gmem.c:218) ==50914== by 0x49C1013: g_slice_free1 (gslice.c:1183) ==50914== by 0x4990DE4: g_error_free (gerror.c:870) ==50914== by 0x4990FE9: g_clear_error (gerror.c:1052) ==50914== by 0x1A489780: _get_gl_context (gtkgstglwidget.c:540) ==50914== by 0x1A4863CB: gst_gtk_invoke_func (gstgtkutils.c:39) ==50914== by 0x49A3834: g_main_context_invoke_full (gmain.c:6137) ==50914== by 0x1A486450: gst_gtk_invoke_on_main (gstgtkutils.c:59) ==50914== by 0x1A48A29E: gtk_gst_gl_widget_init_winsys (gtkgstglwidget.c:632) ==50914== by 0x1A4887E7: gst_gtk_gl_sink_start (gstgtkglsink.c:267) ==50914== by 0x6579810: gst_base_sink_change_state (gstbasesink.c:5662) ==50914== Block was alloc'd at ==50914== at 0x484586F: malloc (vg_replace_malloc.c:381) ==50914== by 0x49A9278: g_malloc (gmem.c:125) ==50914== by 0x49C1BA5: g_slice_alloc (gslice.c:1072) ==50914== by 0x49C3BCC: g_slice_alloc0 (gslice.c:1098) ==50914== by 0x499096B: g_error_allocate (gerror.c:708) ==50914== by 0x4990AF1: UnknownInlinedFun (gerror.c:722) ==50914== by 0x4990AF1: g_error_copy (gerror.c:892) ==50914== by 0x4C4B9F9: gtk_gl_area_set_error (gtkglarea.c:1036) ==50914== by 0x4C4BAF7: gtk_gl_area_real_create_context (gtkglarea.c:346) ==50914== by 0x4B21B28: _gtk_marshal_OBJECT__VOIDv (gtkmarshalers.c:2730) ==50914== by 0x4920B78: UnknownInlinedFun (gclosure.c:893) ==50914== by 0x4920B78: g_signal_emit_valist (gsignal.c:3406) ==50914== by 0x4920CB2: g_signal_emit (gsignal.c:3553) ==50914== by 0x4C4B927: gtk_gl_area_realize (gtkglarea.c:308) Reproduced by running: MESA_GL_VERSION_OVERRIDE=2.7 totem See https://gitlab.gnome.org/GNOME/totem/-/issues/522 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2565>		2022-06-07 17:36:26 +02:00
