I've been attempting to get the following FFI call to work without much 
luck...

Call glGetIntegerv(GLenum pname, GLint *params) using the following:

(let ((gl-int-size (ccl::foreign-size :<GL>int :bytes)))
   (ccl::%stack-block ((return-value gl-int-size))
     (#_glGetIntegerv #$GL_MAX_LIST_NESTING return-value)
     (ccl::%get-unsigned-long return-value)))

The result is the kernel debugger:

? Unhandled exception 11 at 0x92e97ba0, context->regs at #xf0805498
Read operation to unmapped address 0xab0
  In foreign code at address 0x92e97ba0
? for help
[28544] OpenMCL kernel debugger:

What am I missing here?

Thanks,
Phil
