[lldb-dev] PATCH for REVIEW - Fix [Bug 15038] LLDB does not support printing wide-character variables on Linux

[Thirumurthi, Ashok]

The root cause for Bug 15038 is a ptrace EIO that can occur because we don't know the size of a (UTF) string and so read a fixed number of characters for strings.  The attached fix accepts EIO in the case where data has been read and a null terminator of the correct size and alignment was found.

             Bug #: 15038
           Summary: LLDB does not support printing wide-character
                    variables on Linux
           Product: lldb
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs
        AssignedTo: lldb-dev at cs.uiuc.edu
        ReportedBy: daniel.malea at intel.com
    Classification: Unclassified


Printing a variable of wchar_t type does not behave as expected and results in garbage being printed on the screen.

To reproduce, remove the @expectedFailureLinux decorator from TestChar1632T.py and TestCxxWCharT.py and run:

python dotest.py --executable <path-to-lldb> lang/cpp/char1632_t lang/cpp/wchar_t
