[GitHub] [tvm] XIAO-XIA opened a new issue #7682: [BUG][Threefry] Seg fault when running threefry_generate with some out_shape

XIAO-XIA opened a new issue #7682:
URL: https://github.com/apache/tvm/issues/7682


   Segmentation fault occurs when the `out_shape` of `threefry_generate` setted to some cases.
   
   ### To Reproduce
   #### environment:
   Ubuntu 18.04, llvm version 8.0.1
   #### script:
   ```python
   import tvm
   import tvm.relay
   import tvm.testing
   import tvm.topi
   import numpy as np
   
   
   def threefry_generate(target, ctx, gen, size):
       gen_placeholder = tvm.te.placeholder(gen.shape, name="gen", dtype="uint64")
       left_placeholder, right_placeholder = tvm.topi.random.threefry_generate(gen_placeholder, size)
       s = tvm.topi.generic.schedule_extern([left_placeholder, right_placeholder])
       f = tvm.build(s, [gen_placeholder, left_placeholder, right_placeholder])
       out_gen = tvm.nd.array(np.zeros(gen.shape, dtype="uint64"))
       rands = tvm.nd.array(np.zeros(size, dtype="uint64"))
       f(tvm.nd.array(gen), out_gen, rands)
       return out_gen.asnumpy(), rands.asnumpy()
   
   
   @tvm.testing.parametrize_targets
   def test_threefry_generate(target, ctx):
       gen = tvm.relay.random.threefry_key(0).data.asnumpy()
       shape = (1, 3, 224, 224)
   
       a, rands = threefry_generate(target, ctx, gen, shape)
   
   
   if __name__ == "__main__":
       test_threefry_generate(tvm.target.Target("llvm"), tvm.context("cpu"))
   
   ```
   #### error outputs:
   ```
   malloc(): memory corruption
   Aborted (core dumped)
   ```
   #### error cases:
   `out_shape = (1, 3, 224, 224), (1, 3, 32, 32), (1, 3, 16, 16)`
