Right, I see. Though - why is this only an issue for the clang-repl binary and 
not the other clang-based ones? Does it happen to hit some maximum when it uses 
both everything that is in normal clang, plus all the JIT stuff? (Normally I 
would expect LLDB to be the largest one, as it includes much of Clang, but 
that's also always split into a separate liblldb.so.)
