            Bug ID: 16575
           Summary: LLDB on Linux crashes when the inferior generates a
                    signal and hits a breakpoint
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu
          Reporter: daniel.malea at intel.com
    Classification: Unclassified

When the inferior generates a signal (to itself) and hits a breakpoint, LLDB
crashes with an assertion failure:


Test signal and a (1 second delay) breakpoint in multiple threads. ... python:
../tools/lldb/source/Plugins/Process/Linux/ProcessMonitor.cpp:1484: static
ProcessMessage ProcessMonitor::MonitorSIGTRAP(ProcessMonitor *, const siginfo_t
*, lldb::pid_t): Assertion `false && "Unexpected SIGTRAP code!"' failed.


To reproduce, uncomment the corresponding @skipIfLinux from the
test_signal_delay_break_dwarf test case in TestConcurrentEvents.py and run:

python dotest.py --executable <path-to-lldb> -p TestConcurrentEvents
