Even with only dives/test0.xml loaded it loops around these lines, with 
the same values over and over (according to gdb):

deco_allowed_depth (tissues_tolerance=8.7201164053871253e+256, 
surface_pressure=1.0129999999999999, dive=0x1022b8270, smooth=1) at 
deco.c:292
292        while(!below_gradient_limit)
294            if (!smooth)
297                mydata.pressure += PRESSURE_CHANGE_3M / 30; /* 4in / 
10cm instead */
298            new_gradient_factor = gradient_factor_calculation(&mydata);
