[Scip] SCIP binary holding output back?

Dear Ramon,
this is exactly the same thing we already discussed two weeks ago: SCIP
is not holding any output back, but a root node heuristic is called and
seems to take a huge amount of time. I would guess it is the subnlp
heuristic, but you could check this if you would print the statistics
after solving a problem (or stopping the solving process). You just need
to type "print stat" in the interactive shell. Then, you will see which
plugin consumes how much time.
During the heuristic call, no output is printed, because it is just a
subroutine and the branch-and-bound process doesn't proceed. If you
press CTRL-C, SCIP interrupts the heuristic and finishes the current
node, so that you get some output before the solving process is really
interrupted.
Looking at your output below, I can see that you have a primal bound
now, but you didn't copy the line where it is first listed and which
also lists the heuristic responsible for it. Thus, I can only guess that
the heuristic running so long might have found it, so it might even be
worth the long running time. But all of this would be clearer if you
would print the statistics.
Best,
Gerald
