            Bug ID: 24497
           Summary: Single stepping over an instruction that jumps to
                    invalid memory fails on Android arm
           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: labath at google.com
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

This happens because of software single stepping, where we attempt to follow
the instruction and set a breakpoint in the invalid memory (and fail). Things
start falling apart after that. I have made TestCrashDuringStep to demostrate
this.

The expected behavior is to report the crash correctly.
