Subject: [PATCH] Avoid integer overflow

pinpoint is affected by a possible integer overflow, that was also
found and patched upstream in gtk+
https://git.gnome.org/browse/gtk+/commit/?id=894b1ae76a32720f4bb3d39cf460402e3ce331d6

With g_malloc_m we can avoid the integer overflow.

As pointed out by Pacho Ramos in
