bugfix: memory corruption due to sizeof (dstr)
This was reportd by Jeremy Brubaker along with a working
patch. I reworked it to a shorter fix. Jeremy is using
GCC 13.3.1, Evidently, the sizeof a struct which has a
flexible array member is not the same as the offsetof that
member, which we are relying on. I have to research more into
this because ISO C seems to require them to be the same.
* pw.c (dstr_of, dsgrow): use offsetof (struct dsr, str)
rather than sizeof (dstr) when displacing the string pointer
back to the header, and when allocating the space.
