Bug 1962215

Created attachment 1784834 [details]
Video showing the crash with the snippet provided in the description.

Description of problem:

GTK3 crashes on resizing a tree/table column to width 0.

Version-Release number of selected component (if applicable):

3.22.30 (RPM version: gtk3-3.22.30-3.el7.x86_64)

How reproducible:

Compile and run the provided snippet.

Steps to Reproduce:
1. Compile and run the following snippet:
#include <gtk/gtk.h>

// gcc -g table_scrollbar_errors.cpp  `pkg-config --cflags --libs gtk+-3.0` -o TableScrollbarErrors && ./TableScrollbarErrors

enum
{
  STRING_COLUMN1,
  STRING_COLUMN2,
  STRING_COLUMN3,
  NUM_COLS
};


int
main (int argc, char **argv)
{
  GtkWidget *window, *scrolled_window, *view;
  GtkTreeIter iter;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  g_signal_connect(window, "delete_event", gtk_main_quit, NULL);
  gtk_window_set_default_size(GTK_WINDOW(window), 200, 200);

  scrolled_window = gtk_scrolled_window_new (NULL, NULL);

  GtkCellRenderer     *renderer;
  GtkListStore        *liststore;

  liststore = gtk_list_store_new(NUM_COLS, G_TYPE_STRING, G_TYPE_STRING, G_TYPE_STRING);

  view = gtk_tree_view_new_with_model(GTK_TREE_MODEL(liststore));


  renderer = gtk_cell_renderer_text_new();
  gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view), -1, "column1", renderer, "text", STRING_COLUMN1, NULL);
  gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view), -1, "column2", renderer, "text", STRING_COLUMN2, NULL);
  gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (view), -1, "column3", renderer, "text", STRING_COLUMN3, NULL);
  for (int i = 0; i < 3; ++i) {
    GtkTreeViewColumn   *col = gtk_tree_view_get_column (GTK_TREE_VIEW (view), i);
    gtk_tree_view_column_set_resizable(col, TRUE);
  }

  for (int i = 0; i < 10; ++i) {
    gtk_list_store_append(liststore, &iter);
    gtk_list_store_set(liststore, &iter, 
                           STRING_COLUMN1, "item1",
                           STRING_COLUMN2, "item2",
                           STRING_COLUMN3, "item3",  -1);
  }

  gtk_tree_view_set_model (GTK_TREE_VIEW (view), GTK_TREE_MODEL (liststore));

  gtk_container_add(GTK_CONTAINER(window), scrolled_window);
  gtk_container_add(GTK_CONTAINER(scrolled_window), view);

  gtk_widget_show_all(window);
 
  gtk_main();

  return 0;
}
(can be compiled e.g. with "gcc -g table.cpp  `pkg-config --cflags --libs gtk+-3.0`  -o TableExample")
2. Resize the first column to 0 width.
3. Observe crash with assertion error:

(TableScrollbarErrors:15278): Gtk-WARNING **: 15:29:34.645: Negative content width -8 (allocation 2, extents 5x5) while allocating gadget (node button, owner GtkButton)
**
Gtk:ERROR:gtkcellrenderer.c:1787:gtk_cell_renderer_get_aligned_area: assertion failed: (aligned_area->x >= cell_area->x && aligned_area->x <= cell_area->x + cell_area->width)
Aborted (core dumped)

Actual results:

Application crashes.

Expected results:

Application does not crash.
