...needed to build CoreCLR for ARM32. Hi Mason, I did see the bug, but I have to say that, as priorities go, that's way too low on my list to go past the initial look. I compiled your test on a Cortex-A15 / Linux with Clang-3.8 (trunk) and GCC 4.8.2 and on both occasions, the program crashes on _Unwind_VRS_Pop() while stepping. I, then, left it for the unwinding experts, which I'm not. > This is a blocking problem for us, and I > was just wondering how things are coming on it?

Well, yes, an unwinding expert *was* who I was really hoping to hear from. But if I understand correctly, you're saying that rather than seeing the values Ben reported, the sample code crashes on you...

Hi all, I'm working on the CoreCLR project, coordinating a community effort to produce an Android port of Microsoft's open-source version of the CLR.  A major part of that is getting everything to run on the ARM32 architecture, which is by far the most common CPU for Android devices. A couple weeks ago, Ben Pye, a developer working on the ARM32 stuff, found and reported a bug related to

I know that unw_step() calls _Unwind_VRS_Pop() while loading the stack frame, because you need the context of that frame, so for me that looked like a good thing to say. If you report a bug in the unwinder, I expect you to either understand a bit about it (like me), or to have someone at your disposal that do. I cannot dig the problem for you...
