[Bug] import tvm before pytorch leads to core dump at the end

[mikeseven]

Expected behavior

order of import should not matter

Actual behavior

import tvm
import torch

At the end, the application quits with

free(): invalid pointer
Aborted (core dumped)

However, importing tvm after all other imports works

import torch
import tvm

To reproduce, there is no need to even do anything with tvm in the code!

Environment

TVM main branch, same error with latest tags too

• same error built with or without cuda
• same error built with llvm-config --link-static or without

Ubuntu 20.04, x86
tested with clean conda environment with pytorch 1.11 and 1.12 + cudatoolkit

This was discussed in #9362 and mitigation documented in #9433.

[mikeseven]

yes I used this mitigation but it didn't work.
I sync'd today and rebuild and it now works....

[zky001]

yes I meet same bugs and haven't found true reason
