The only errors I see are 2.18 constructions when run with 2.19.49.
OTOH I always see these warnings:
warning: cannot find property type-check for `extra-X-extent' (backend-type?).  
perhaps a typing error?
warning: skipping assignment
Seven in all.

Oh well, I'll just add my benchmarks:

real    3m13.656s
user    3m8.708s
sys     0m1.832s

2008-vintage Intel Core2 Duo processor, 1.20GHz, 2GB memory.

real    3m28.626s
user    3m26.885s
sys     0m1.532s

2006-vintage Intel Pentium 4 CPU 3.00GHz, 2GB memory.

Ages surmised from the BIOS dates. Time to cadge another computer methinks!

Cheers,
David.
