ponyc: Compile error: "Pass 'Move heap allocations to the stack' is not initialized"

I’ve just tried to build trivial helloworld from tutorial, and it fails to compile. I’ve tried the build from bintray and manually compiled, all of the output something like this:

Building builtin ->
/home/avsej/.local/lib/pony/0.3.1-1-g8a8ee28/packages/builtin

Although when I disable optimizations (-d) it works as expected

The problem only arises with optimization. If I use --debug with ponyc it works fine.

So then I saw this: http://stackoverflow.com/questions/30114849/crash-on-au-addrequiredloopinfo-in-llvm-pass

And tried this:

diff --git a/src/libponyc/codegen/genopt.cc b/src/libponyc/codegen/genopt.cc
index 9a43610..ab367d9 100644

   PassManagerBase& pm)
 {
   if(pmb.OptLevel >= 2)
+    pm.add(new DominatorTreeWrapperPass());
     pm.add(new HeapToStack());
 }

…and now it works!
