<div>Dear Community,</div>

<div>The <a href="https://github.com/CausalityLtd/ponyc/tree/llvm37" target="_blank">
ponyc</a> (llvm37 branch) project is facing an issue on Windows:</div>
<div><br>
</div>
<div>When optimizations are turned on (llvm 3.7.0-final and <a href="https://github.com/CausalityLtd/ponyc/blob/llvm37/src/libponyc/codegen/genopt.cc" target="_blank">more specifically</a>, opt-level 3, BBVectorize, LoopVectorize, SLPVectorize, RerollLoops,
LoadCombine + a custom heap to stack pass) writing an object file aborts (on Windows only) with the following fatal error:</div>
<div><br>
</div>
<div>“Starting a function before ending the previous one!” at MCStreamer.cpp:407 during LLVMTargetMachineEmitToFile. Verifying the IR with llc raises no errors.</div>
<div><br>
</div>
<div>What exact problem is being detected here and how can we get more details on the location in the IR that is causing the problem?</div>
<div><br>
</div>
<div>Turning off optimizations successfully writes the object file. This only occurs on Windows, writing object files works fine on Linux and OS X.</div>
<div><br>
</div>
<div>Is this a know issue with LLVM 3.7.0-final and how can this be fixed? Is a patch required?</div>
<div><br>
