            Bug ID: 20281
           Summary: readline.so module is not built when running 'ninja
                    lldb' on Linux
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu

This probably affects FreeBSD as well.

The readline.so Python Module (not libreadline system library) is needed on
Linux to avoid the crash issue with Python's stock readline module and libedit.
 It needs to be built and installed in the lldb lib dir any time liblldb.so (or
a static equivalent) is considered needed.

Currently, running 'ninja lldb' is not building the readline module.  This
surfaces the broken behavior of using the system Python readline module.

(Having the python readline.so, which links against libreadline.so on
non-MacOSX platforms, in a program which also uses libedit.so, causes havoc in
some libedit readline compatibility mode crossover with the real
libreadline.so).
