ganler opened a new issue, #13048:
URL: https://github.com/apache/tvm/issues/13048

   ### Expected behavior
   
   `cast<int32>( cast<bool>(-1i64) )` should be `1`.
   
   ### Actual behavior
   
   `cast<int32>( cast<bool>(-1i64) )` returns wrong results (i.e., `-1`) in 
optimized graph runtime.
   
   ### 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
   
   i0 = relay.var("i0", shape=(1,), dtype="int64")
   cast_bool = relay.cast(i0, "bool")
   cast_int32 = relay.cast(cast_bool, "int32")
   
   f = relay.Function([i0], cast_int32)
   input = np.array([-1], dtype="int64")
   opt_res = relay.create_executor("graph", device=tvm.cpu()).evaluate(f)(input)
   debug_res = relay.create_executor("debug", 
device=tvm.cpu()).evaluate(f)(input)
   print(f"debug_res: \t{debug_res}") # [-1]
   print(f"opt_res: \t{opt_res}")     # [1]
   ```
