            Bug ID: 45981
           Summary: StringRef::getAsInteger doesn't support "+1"
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: jingham at apple.com
                CC: jdevlieghere at apple.com, llvm-bugs at lists.llvm.org

(lldb) set set interpreter.expand-regex-aliases 1
(lldb) jump +1
thread jump --by +1
error: invalid line offset: '+1'.

And indeed:

(lldb) thread jump --by +1
error: invalid line offset: '+1'.

The option parser calls:

option_arg.getAsInteger(0, m_line_offset);

where m_line_offset it the storage for the integer read in.  Either
StringRef::getAsInteger should support this, or we should strip off the leading
+.
