My fault.  I changed the code because there was enough memory
allocated for accommodating the I/O.  I backed the change out again,
even though I have no idea why it would cause a problem.  Could you
alternatively try removing the "+ carryover" from the argument to
alloca a few lines above, and see whether this would again cause the
crashes you experienced?

I hate it if one has to allocate more memory than properly needed,
this points to a thinko or possibly other problem elsewhere.
