   Thanks for reporting the problem, please open a new thread on https://discuss.tvm.apache.org/. BTW, checking a modified version of the script on master seems to show a stable memory usage.
   
   ```python
   import os, psutil
   import tvm
   from tvm import te
   
   def tvm_build():
       n = 2
       A = te.placeholder((n,), name='A')
       B = te.placeholder((n,), name='B')
       C = te.compute(A.shape, lambda *i: A(*i) + B(*i), name='C')
       s = te.create_schedule(C.op)
       m = tvm.driver.lower(s, [A, B, C], name="test_add")
       rt_mod = tvm.driver.build(m, target="llvm")
   
   def main():
       process = psutil.Process(os.getpid())
       for i in range(0, 1000):
           tvm_build()
           print('i='+str(i)+', Used Memory:', process.memory_info().rss / 1024 / 1024, 'MB')
   
   
   main()
   ```
