<div class="moz-cite-prefix">Just to circle back here, I did a bit
more digging. I'm not entirely sure how this is supposed to work
- our linking scheme is a bit of a mess - but here would be the
two things I'd try.<br>
<br>
Explicitly include:<br>
#include "llvm/CodeGen/LinkAllCodegenComponents.h"<br>
<br>
Call the functions:<br>
initializeCore(*Registry);<br>
initializeCodeGen(*Registry); <br>
<br>
What I think is happening is that you're getting into the
GCStrategy code without having run the initializers for the
CodeGen library. Not entirely sure how that's possible, but it
appears to be the best explanation for the symptoms. <br>

I need to take a closer look at
your bug report before I can
really comment. </blockquote>
</span> Ok, I took a look. Its hard
for me to tell much from your report.
I don't have Visual Studios (or
Windows for that matter) and can't
easily reproduce. <br>
<br>
It would really help to know if this
is a problem with the C bindings or
the generated IR. If you manually
create the expected IR and run it
through opt/llc, does that work?<br>
<br>
Can you include the full output of
this example? Both the IR and the
error would be useful to see. <br>
<br>
One observation, it looks like you're
using the erlang GC not shadow stack?
e.g. <br>
LLVM.SetGC(sum, "erlang");<br>
