> > @huajsj @tqchen There is a UT "test_te_tesnor.py" failed for this PR, which is a "SegmentFault" in the generated code. Since tvm llvm backend code is generated on the fly (JIT), no binary generated, I couldn't debug it with gdb. Do you have any suggestions? What is the best practice to debug such kind of problems? use lldb? > > @zhuwenxi ， besides of using export_library, sometime I use "python -m pdb" and gdb together to debug generate code issue, hope this information is useful for you. Great! It works, I've found the crash point. (Though it crashes in ndarray.h, rather than llvm ir itself directly) Just curious, if crash happens in the llvm generated code, is gdb still able to report the crash point, exactly which ir crashed? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
