Replying to [comment:5 cremona]:
> This behaviour is supposed to be caught by mwrank C++ code, so that this
can be detected gracefully by using the ok() function.
On looking into it, I see that this will need a patch to the file
src/qrank/mrank1.cc, since I just call abort() when I try to round to a
long int and it overflows. Instead I need to catch that properly. (Pity
C++ does not have the try/except functionality of python).
So this particular bug / behaviour needs to be flagged as "report upstream
(done) and wait for a patch from upstream (on my todo list)".

be dealt with. (There is absolutely no reason to use the interactive
interface when everything can be found from the library interface.)
