Interestingly, I also get a similar error in a different executable (my unittest): pure virtual method called terminate called without an active exception 0 tartc 0x00000001010a8265 PrintStackTrace(void*) + 53 1 tartc 0x00000001010a88cc SignalHandler(int) + 364 2 libSystem.B.dylib 0x00007fff831341ba _sigtramp + 26 3 libSystem.B.dylib 0x7261742e65637365 _sigtramp +

I recently updated my version of LLVM from revision 140108 to 142082, and several things broke, most of which were easily fixed. However, I'm now getting a "pure virtual method called" exception (__cxa_pure_virtual) which I wasn't getting before. This is happening in the destructor of a statically-initialized object. (More precisely, it's blowing up in a BumpPtrAllocator,

I'm trying to track down the problem with the assertion failure in SelectionDAGBuilder.cpp. This is the code: *case* *Intrinsic*::gcroot: *if* (GFI) { *const* Value *Alloca = I.getArgOperand(0); *const* Constant *TypeMap = cast<Constant>(I.getArgOperand(1)); * FrameIndexSDNode *FI = cast<FrameIndexSDNode>(getValue(Alloca).getNode());*

I'm working on the code to handle GC tracing of "intermediate values" (as described in the GC doc), and I've run into a weird problem. (Note, this has nothing to do with the patch I have proposed, this error occurs with regular old pointer-allocas.) The exception I am getting occurs in this code here in SelectionDAGBuilder.cpp: *case* *Intrinsic*::gcroot: *if* (GFI) {

After to speaking to Devang and a number of other people at the developer's conference, I was able to make some forward progress on getting debugging to work. I'm now able to actually single-step through my program and set breakpoints, and examine function parameters. However, I'm also seeing a lot of new problems which weren't exposed before. After spending the better part of two

Hi Talin, I think that the framework for GC assumes llvm.gcroot to be in the first block. If it is not the case in your example, it will break these assumptions.

Well, after some investigation I have a few more clues as to what is going on. I have a module which contains a call to an external native function. This native function lives in a static library, and there is an external declaration for it in the module. I find that I can run "llvm-ld -disable-opts -native -l mylibrary test.bc" and it works fine. That is, llvm-ld is able to
