Bug confirmed.

Any time you see a compiler message starting with "### " (and no other error
messages about incorrect input) that's a compiler crash and usually always
indicates a bug in the translator. 

By the way, the following code is unsafe in general:

    printf("t%d:hullcpy thread of dst->pts=%d\n", MYTHREAD, upc_threadof(dst-
>pts));

upc_threadof() returns a size_t, which is larger than an int on many platforms -
you should always cast the result of upc_*of() to an (int) or (long) before
passing it to printf (and use an appropriate printf format specifier). Otherwise
printf may display garbage on some systems.
