Comment (by dunfield):

 I poked around a bit.  In the first example, the issue seems to be that
 the wrapper is misparsing the correct output of "homchain".  In the second
 example, "homchain" outputs the following abort message (due to integer
 overflow, I think) which is ignored by the wrapper.

 [Tech info: chain 24, addr 8, intgr 2.]
 Reading a chain complex from 'bad.txt'...
 Time used so far: 0.00 sec (0.000 min).
 The ring of coefficients is the ring of integers.
 Computing the homology of the chain complex...
 Reducing D_1: 0 +ERROR: Number out of range (*).
