            Bug ID: 37054
           Summary: MI '-info sharedlibrary' command crash
           Product: lldb
           Version: 6.0
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: dantipov at nvidia.com
                CC: llvm-bugs at lists.llvm.org

To reproduce:

$ ldb-mi 
(gdb)
-file-exec-and-symbols /path/to/executable
^done
(gdb)
=library-loaded,...
-target-attach PID
^done...
(gdb)
-info sharedlibrary
~"From        To          Syms Read   Shared Object Library"
~"0x0000000000400238    0x0000000000411b2c      Yes            
/path/to/executable"
terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid
Aborted (core dumped)

Expected lldb-mi backtrace is:
