Ah-hah, good insight!

The code seems to be fetching a pointer to CurrentMemoryContext from a
PC-relative location; presumably that's a literal that the dynamic
linker is supposed to update at shlib load time. I guess that pointer
is not correctly computed in the other case, or else it's fetching the
wrong pointer value.

Me either, but at least it's something to work from. You might try
diffing the working and non-working -E output from cube.c to see if
there are any changes that obviously affect CurrentMemoryContext.
