Oh, it seems that in current cpython branch this problem is fixed by checking
condition _len(h) > 1:

New submission from Artem Fokin:
Suppose we have the following code:
from heapq import merge
def iterable():
lst = range(10)
for i in xrange(20):
yield lst[i]
it1, it2= iterable(), iterable()
print list(merge(it1, it2)) # no IndexError
