            Bug ID: 20545
           Summary: PythonSynthDataFormatterTestCase.test_with_dwarf_and_r
                    un_command has all 'expect' output on stdout/test log
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu
          Reporter: emaste at freebsd.org
    Classification: Unclassified

Test file:
test/functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py

Initially lldb's output as handled by self.expect() is not sent to stdout /
test log.  After executing
> self.runCmd("script from fooSynthProvider import *")
the output makes it through.

.=success F=fail E=error s=skipped x=expected-fail u=unexpected-success

<<< script command executed here >>>
(foo) f00_1 = (a = 0, fake_a = 16777216, r = 33)
(foo) f00_1 = (a = 0, fake_a = 16777216, r = 33)
(int) f00_1.fake_a = 16777216
(int) f00_1[1] = 16777216

This puts a lot of junk in the log, and confuses the buildbot parser, because
it tries to parse lines starting with "Category: " as test result codes.  See
http://lab.llvm.org:8011/builders/lldb-x86_64-freebsd

output snippet:

error: cannot add filter for type foo when synthetic is defined in same
category!
