GiST: spl_rattr in gistSplit()

[3rd day of trying to track down a SEGV]

In gistSplit() I see:
             newtup[0] = gistFormTuple(giststate, r, v.spl_rattr, v.spl_rattrsize, v.spl_risnull);

but v.spl_rattrsize hasn't been initialized:
 (gdb) p v.spl_rattrsize[0] $136 = -1073749368

Is this going to be a problem?  Eventually we get a GISTENTRY with bad
bytes in gistFormTuple(), but maybe it's never used?
 (gdb) p centry[0] $138 = {key = 137280264, rel = 0x0, page = 0x0, offset = 0, bytes = -1073749368, leafkey = 0 '\0'}
