Comment (by dsm):
FWIW (and for the record) I get slightly different behaviour on an ubuntu
12.04 vbox running on a core duo macbook with 5.1.beta0:
{{{
sage: for i in range(10):
....: try:
....: print erf(45*10**i).n()
....: except:
....: print 'problem'
....:
1.00000000000000
1.00000000000000
1.00000000000000
problem
problem
problem
problem
problem

}}}
where the problem is the same Pari (15) error in the ticket. Pari should
certainly be returning 1 here, although any error is certainly better than
