All of the MemoryContextSwitchTo calls in plpython seem to be in
patterns like this:

MemoryContext oldcontext;

oldcontext = CurrentMemoryContext;
PG_TRY();
{
... do something ...
}
PG_CATCH();
{
MemoryContextSwitchTo(oldcontext);

Since oldcontext is only set in the one place, it really shouldn't
require "volatile" decoration, but maybe it does. Can you do some
testing to see if that would fix it?

(Of course, really plpython's bogus approach to error handling ought
to get thrown out and rewritten from scratch, but that's not happening
right now.)
