@jckarter, is this our negative offset thing?

No idea, sorry. @lhames is this coming from MCJIT?

Is this the LLDB-based REPL or the one in libImmediate? Both are using MCJIT, but this error looks like it's coming from https://github.com/apple/swift-lldb/blob/stable/source/Plugins/SymbolFile/DWARF/SymbolFileDWARF.cpp , so I suspect this is an LLDB/REPL issue rather than an MCJIT specific one.

Yes, it's LLDB. The integrated REPL has a different banner that says it's the integrated REPL.

Yes, it's LLDB. The issue only happens for print(), other output is fine.

The internal REPL is fine:

***  You are running Swift's integrated REPL,  *** 
***  intended for compiler and stdlib          *** 
***  development and testing purposes only.    *** 
***  The full REPL is built as part of LLDB.   ***
