[SCIP] FiberSCIP terminates the solution process without reporting the reason.

[Yuji Shinano]

If it is OK for you, could you give me the instance, the parameters, command line when you ran it
andc also logs you got? I will try to debug it. Please send me the e-mail (not this scip mailing list).

Best regards,
Yuji
