Description Forgotten User 3iFmpWffVQ 2018-03-10 19:24:28 UTC 
When running 'zypper info zypper' or 'zypper search zypper' and immediately interrupting it with C-c, zypper hangs indefinitely and then can only be killed with kill -9.

The cause for bug 1092413 is an undefined behavior which not necessarily leads to a core dump. During testing we also recognized the behavior you describe here.

Bug 1092413 is fixed in
  TUMBLEWEED      zypper 1.14. 5   
  SLE-15          zypper 1.14. 5   
  SLE-12-SP3      zypper 1.13.42   
  SLE-12-SP2      zypper 1.13.42   
  SLE-12-SP1      zypper 1.12.55   
  SLE-12          zypper 1.11.67

This most probably fixes your issue as well. In case it does not, please repoen the bug and attach the /var/log/zypper.log after you had to kill zypper.
