[Sam Bromley]

Subject: libpango1.0-dev: memory leak in pango_layout_get_extents()
Package: libpango1.0-dev
Version: 1.6.0-3
Severity: important

*** Please type your report below this line ***

The following code snippet demonstrates the memory leak.
Defining DO_LEAK enables the leak:

-----------------------------------------
#include <stdlib.h>
#include <stdio.h>
#include <pango/pango.h>
#include <pango/pangoft2.h>

int main(int argc, char *argv[])
{
	PangoContext *context;
	PangoFontMap *fontmap=NULL;
	PangoLayout *layout;
	int dpi = 96;

	g_type_init();

	if (g_file_test("./pangorc", G_FILE_TEST_EXISTS))
		putenv("PANGO_RC_FILE=./pangorc");

	while (1)
	{
	
		/* create a font map */
		fontmap = pango_ft2_font_map_new();

pango_ft2_font_map_set_resolution(PANGO_FT2_FONT_MAP(fontmap),dpi,dpi);
	
		/* create a context */
		context =
pango_ft2_font_map_create_context(PANGO_FT2_FONT_MAP(fontmap));

		/* free the fontmap */
		g_object_unref(fontmap);
	
		/* make a layout */
		layout = pango_layout_new(context);
#ifdef DO_LEAK
		PangoRectangle logical_rect;
		pango_layout_get_extents(layout, NULL, &logical_rect);
#endif
	
		/* free the layout */
		g_object_unref(layout);

		/* free the context */
		g_object_unref(context);
	}
	
	return EXIT_SUCCESS;
}
