With the help of iain at codesourcery.com and andrew.kaylor at intel.com we tracked the problem down to a bad relocation that was clobbering the first bytes of the eh_frame. I think this problem/solution may be OS X specific. On akaylor's suggestion I made the change below and my reproducable test case now compiles fine with MCJIT. As well, my Common Lisp code base now compiles using MCJIT - that's about 1,000 functions at one MCJIT module per function. In llvm/lib/ExecutionEngine/RuntimeDyld Index: RuntimeDyldImpl.h...

Hi, There may be two problems with __register_frame usage. However based on http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-April/061768.html I think the existing code is correct for OS-X but likely buggy for Linux and Windows systems. Your crash is on OS-X, right? Anyhow, the first problem is very easy to fix. On Linux and Windows (at least) __register_frame should be called once and not

.... I had a quick chat with Tim Northover about this and our guess was that it had something to do with relocations being applied more than once? Cheers, Lang.
