jikechao opened a new issue, #17348:
URL: https://github.com/apache/tvm/issues/17348
### Actual behavior
```shell
...
[09:37:39] /software/tvm/src/runtime/relax_vm/vm.cc:735:
pc = 21, execute: vm.builtin.alloc_tensor
Segmentation fault (core dumped)
```
### Steps to reproduce
```python
import tvm
from tvm import relax
import numpy as np
from tvm.script import ir as I
from tvm.script import tir as T
from tvm.script import relax as R
@I.ir_module
class Module:
@R.function
def main(cond: R.Tensor((), dtype="bool"), x: R.Tensor((1,),
dtype="float32")) -> R.Tensor((4703,), dtype="float32"):
cls = Module
if cond:
gv = R.add(x,x)
gv1 = R.add(x,x)
y_then = R.multiply(gv,gv1)
y: R.Tensor((1,), dtype="float32") = y_then
else:
gv3 = R.multiply(x,x)
gv4 = R.multiply(x,x)
y_else = R.add(gv3,gv4)
y: R.Tensor((1,), dtype="float32") = y_else
return y
mod = Module
mod = relax.transform.DeadCodeElimination()(mod)
#mod = relax.transform.LegalizeOps()(mod)
mod.show()
def compile_mod(mod, func_name, target, *inputs):
ex = relax.build(mod, target='llvm')
vm = relax.VirtualMachine(ex, tvm.cpu())
mod_outputs = vm[f'{func_name}'](*inputs) # segfault here!!
input_0 = tvm.nd.array(np.bool_(False))
input_1 = tvm.nd.array(10 * np.random.random([1]).astype('float32'))
compile_mod(mod, 'main', 'llvm', input_0,input_1)
```
