<pre>To reproduce, remove the @skipIfDarwin decorator from TestLongjmp.py and run:
python dotest.py --executable <path-to-lldb> -p TestLongJmp
The crash is due to one of two assertion failures:
Assertion failed: (!"Didn't get sequence mutex for read register."), function
ReadRegisterBytes, file
/Users/daniel/dev/lldb/source/Plugins/Process/gdb-remote/GDBRemoteRegisterContext.cpp,
line 255
or
Assertion failed: (m_failure_message.empty()), function Unlock, file
/Users/daniel/dev/lldb/source/Host/common/Mutex.cpp, line 353
The problem does not seem reproducible on Linux, but happens on Mac OS X
regardless of the test compiler used (I tried ICC and Clang).</pre>
