But now, `error_desc' is leaking in the case you xmalloc it.
When you fix that leak, you'll stumble of the fact that
in some cases you have this:

 ts->error_desc = ""

while in others you have this:

 ts->error_desc = (char *) xmalloc (p2 - p1 + 1);

How can you reliably know if you may xfree
ts->error_desc that way?  xfree ("") is a no go.
Comparing a pointer with "" is also not good.
