            Bug ID: 23994
           Summary: lldb fails to call a function in the target, and
                    prints a nonsensical error message
           Product: lldb
           Version: unspecified
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu
          Reporter: tlbowman1235 at gmail.com
    Classification: Unclassified

I am debugging an app on Yosemite with lldb-320.4.156, and any time I attempt
to call a function in the target, i.e. something like "expr hello()" or "print
var.func()", lldb spits out the following error message:

error: 0 errors parsing expression
error: error: 0 errors parsing expression
error: no matching function for call to 'strlen'
note: candidate function not viable: requires 2 arguments, but 1 was provided
error: 1 errors parsing expression
error: 1 errors parsing expression

Unfortunately, this bug only occurs when debugging one specific app, so I don't
think there is much hope of anybody else reproducing this. But maybe somebody
at least has a clue as to what might cause it?
