I've been thninking about this issue for some while now as well, and I've written (in gtkmm straight, so i didn't attempt to provide patches yet) a CairoImageSurface cellrenderer, and a few miscellaneous widgets which render directly a Cairo ImageSurface to a drawable instead of doing roundtrips.

That's pretty much a no-go. g_assert_warning is marked G_GNUC_NORETURN. If you return from such a function, there is no telling what incorrect assumption the following code was compiled with, i.e., things that the compiler thought were in registers all of a sudden are not. Crash. Burn. Toast.

Hey, Why not introduce a new check, some g_check_stuff() which would do what you propose? And let g_assert() be what it is, a glib analog of C assert(). When an assertion fails, you can't possibly expect the code to function in any meaningful way, e.g. int idx; g_assert (idx >= 0); array[idx

hey All. i'd like to propose to turn g_assert and friends like g_assert_not_reached into warnings instead of errors. i'll give a bit of background before the details though. the main reasons we use g_return_if_fail massively throughout the glib and gtk+ code base is that it catches API misuses v
