It's a bug in Pango::Context::get_font_map(). It should get its own
reference to the font map, but it doesn't. Until the bug has been fixed
in pangomm, you can add a reference yourself.
auto fontMap = context->get_font_map();
fontMap->reference(); // Temporary bug fix
Note that when you start using a fixed version of pangomm, the call to
fontMap->reference() will cause a memory leak.
