I’ve been updating SAFECode files to work with LLVM 3.7, and I’ve
run into a number of errors I can’t explain.</blockquote>

You might want to see if the "const" qualifier is causing the
problem. The ostream is a basic_ostream<char> while the
string you're passing is a "const char".<br>
<br>
Regarding the comment about using LLVM's stream classes, the code
you're working on is a runtime library linked into applications and
is not an LLVM compiler pass. Therefore, using std::ostream should
be fine (at least, it shouldn't be the cause of the problem).<br>

<div class="">In
LLVM_SRC/projects/safecode/runtime/BBRuntime/DebugReport.cpp,
there are a host of std::ostream objects that, when given
strings with the “<<“ operator, produce errors. Also,
the compiler doesn’t seem to recognize std::dec for some
reason. Here is a sample of the errors I’m getting:</div>

<div class="">I’ve been trying to find information online, but
