Like Eli says, this really should be fixed in doprint.c.

However, since this is a crash that makes Emacs unusable, and since (as
you point out) sprintf is unproblematic here, I'm fine with applying the
patch.  Perhaps with a FIXME comment about how this should your esprintf
once doprintf has been fixed.
