[llvm-dev] EH failures in MCJIT

[Krzysztof Parzyszek via llvm-dev]

After re-cmaking and rebuilding everything from scratch, I'm seeing 
failures in MCJIT.  It this something known or expected?  I build 
LLVM/clang with pre-packaged clang-3.7.0, with "-stdlib=libc++".


Example failure:

/w/bld/org/./bin/lli -remote-mcjit 
-mcjit-remote-process=/w/bld/org/./bin/lli-child-target 
/w/src/llvm.org/test/ExecutionEngine/MCJIT/remote/eh.ll
--
Exit Code: 184

Command Output (stderr):
--
warning: remote mcjit does not support lazy compilation
terminating with uncaught exception of type int
ERROR: Unexpected RPC call
