            Bug ID: 34510
           Summary: Minidump target does not resolve new symbols correctly
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at lists.llvm.org
          Reporter: mosescu at google.com

Once frames are "symbolized" they will not get re-symbolized if modules/symbols
are added later on. For example:

target create --core "foo.dmp"
image add full/libcontent.so
image load --file libcontent.so --slide 0x00007f17fc361000

Here I add libcontent.so explicitly but since the frames are cached from the
first bt, the bt after the image load will not use the new symbols. 

As far as I can tell this is due to the explicit disabling of
ClearStackFrames() in ThreadMinidump.
