This probably means that the GType width is wrong for 64 bits, which is not entirely unexpected since it is defined like this:
#if GLIB_SIZEOF_SIZE_T != GLIB_SIZEOF_LONG || !defined __cplusplus typedef gsize GType; #else /* for historic reasons, C++ links against gulong GTypes */ typedef gulong GType; #endif which means it can be either an uint (at least I hope gsize is consistently uint) or an ulong. On 32 bit machine they are the same, on 64 bit not. I had assumed that the first branch is the usual and defined gtype as gsize/uint. An easy fix would be to change (cffi:defctype gtype gsize) to (cffi:defctype gtype gulong). But that might break this on some other systems. Since I am not sure how to detect this without invoking the C compiler, I have now added the change as a controllable feature with ulong as a default and pushed to the repository. Please test it and report if it fixes the memory fault.
