ganler opened a new issue, #13044:
URL: https://github.com/apache/tvm/issues/13044

   ### Expected behavior
   
   Compiled binary should be executable.
   
   ### Actual behavior
   
   Graph runtime terminates at runtime after compiling a valid model due to failed integer type checking. Similar issue: https://github.com/apache/tvm/issues/11794
   
   ### Environment
   
   https://github.com/apache/tvm/commit/fa17da22c73fb9e95c27e4c28130835b628caf6b on Ubuntu 20.04.
   
   ### Steps to reproduce
   
   Preferably a minimal script to cause the issue to occur.
   
   ```python
   import tvm
   from tvm import relay
   import numpy as np
   
   """
   fn (%i0: Tensor[(1, 1), int32]) {
     %0 = broadcast_to(%i0, shape=[1i64, 1i64]);
     %1 = subtract(%0, %i0);
     argmax(%1, axis=[1])
   }
   """
   
   i0 = relay.var("i0", shape=(1, 1), dtype="int32")
   v0 = relay.broadcast_to(i0, relay.const([1, 1], dtype="int64"))
   v1 = relay.subtract(v0, i0)
   v2 = relay.argmax(v1, axis=[1])
   
   f = relay.Function([i0], v2)
   relay.create_executor("graph", device=tvm.cpu(), target="llvm").evaluate(f)(
       np.zeros((1, 1), dtype="int32")
   )
   
   """
     Check failed: ret == 0 (-1 vs. 0) : Assert fail: 
     (((tir.tvm_struct_get(arg.T_subtract_red, 0, 5) == (uint8)0) && 
     (tir.tvm_struct_get(arg.T_subtract_red, 0, 6) == (uint8)64)) && 
     (tir.tvm_struct_get(arg.T_subtract_red, 0, 7) == (uint16)1)), 
     arg.T_subtract_red.dtype is expected to be int64
   """
   ```
