for call in calls:
    b, x, restrt, work, work2, iter_, resid, info, ndx1, ndx2, ijob = call

    x, iter_, resid, info, ndx1, ndx2, sclr1, sclr2, ijob = \
        dgmresrevcom(b, x, restrt, work, work2, iter_, resid, info, ndx1, ndx2, ijob)

for p in (x, iter_, resid, info, ndx1, ndx2, sclr1, sclr2, ijob):
    print(repr(p))

What's particularly frustrating is that revcom appears to be state-dependent, which means that it's much more work to extract into fortran.

@isuruf Do you know how f2py could preserve state between the function calls?
