Ok, finally see the bug.  I was mislead by looking at second sprintf in the
routine, but that one is optimized out and there is a third one, which is
bogus:

                if (currseg->placeholder) {
                        sprintf(statement, "%s$%d", statement,
currseg->placeholder);
                }

You simply can't do this in C, see ISO C99, 7.19.6.6:
If copying takes place between objects that overlap, the behavior is undefined.

I certainly don't have time to rewrite this whole junk, so here is just
a quick fix for this exact case, though someone please rewrite this, ideally
from scratch.
