            Bug ID: 16016
           Summary: LLDB sometimes asserts when calling
                    SBProcess::Resume() on Linux
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu
          Reporter: daniel.malea at intel.com
    Classification: Unclassified

The bug seems to be in the Linux process plugin; my feeling is that it points
to a race condition in the plugin, as it happens non-deterministically.

The assertion failure is:

ProcessPOSIX.cpp:259: virtual lldb_private::Error ProcessPOSIX::DoResume():
Assertion `state == eStateStopped || state == eStateCrashed' failed.

To reproduce, run:

python dotest.py --executable <path-to-lldb> api/multithreaded/ 

NOTE: if the problem does not reproduce initially, try running dotest.py -#10
to run the test 10 times.


The test case in question is test_listener_resume.cpp which spawns a secondary
thread to handle SBListener events and calls Resume() on the process retrieved
from the event.
