If this patch introduced textlow/texthigh, then I think there's
good reason to suspect that removing it will make this problem go away
since it's the loss of synchronisation between the cached versions
of textlow/texthigh and those in the struct psymtab that appears to
be the problem.

However, I'm not sure if undoing this patch is the way to go since
you're not sure what Jim was trying to accomplish. I don't know enough
at this point to decide.

I'm not sure what you mean here.

For the moment, I'm going to try to resynchronise the cache values. The
code compiles, but I won't be able to try it until to tomorrow.
