Not really, cf.

I've seen an earlier report already and will do a test build as a matter
of interest to see why it triggered around the MIPS change only, once I'm
done with the current stuff.

Is it caused by this patch? It seems to be only MIPS-related, otherwise
we'd get reports from other 32bit arches in case of the emulated 64bit
division.

If you'd like to get that analyzed in the sources, please post the
snippet related to the binary address .text+0xf14 or .text+0xf6c .
