test commit: [bd1be8a](https://github.com/llvm/llvm-project/commit/bd1be8a242384d98ef2087f4571b464e01501f5a)
step to reproduce:
`
mlir-opt test.mlir --test-tensor-copy-insertion="bufferize-function-boundaries"
`
test case:
```
module {
func.func @example(%arg0: tensor<2x3xi32>) -> tensor<2x3xi32> {
return %arg0 : tensor<2x3xi32>
}
func.func @main(%arg0: tensor<2x3xi32>) {
%0 = call @example(%arg0) : (tensor<2x3xi32>) -> tensor<2x3xi32>
llvm.return
}
}
```
Crash backtrace:
```
