RuntimeError: out of bounds memory access when using plugin on a large nested AST

[jzhan-canva]

Describe the bug

When a large nested file being loaded to swc with plugin, the plugin_runner will crash.
When same file being loaded to swc without plugin, no error is thrown.

Input code

export result = {
      output: outputBuilder()
        .addConfig(1)
        .addConfig(2)
        .addConfig(3)
        .addConfig(4)
        .addConfig(5)
        ....
        .addConfig(1500)
        .build(),
    }

Config

{
  "$schema": "https://swc.rs/schema.json",
  "jsc": {
    "experimental": {
      "plugins": [["@swc/plugin-noop", {}]]
    }
  }
}

upon further investigation, it seems the bug only happen when AST tree is too deep, not the breadth
for example in the reproducible example, I have a builder with 1000+ depth member expression, and it trigger the issue
but if I reduce depth, I can duplicate the builder code many times without any issue

So my guess is that it's about stack overflow rather than a memory usage. Stack sizes are limited, and I think rkyv is failing due to the nested call level being too deep.

I believe we have same issues in the host as well? if depth is deep enough, either host or plugin won't able to traverse down with visitor.

[jzhan-canva]

Right now the host and guest have different limit. I think it makes sense to have same limit for host and guest

[jzhan-canva]

Current host limit is bigger, so the identical file can run without plugin but not with plugin

[kwonoj]

I think it makes sense to have same limit for host and guest

I'm not sure if this is configurable on our end, ideally hope to do so.

[kdy1]

No, I mean it's failing with rkyv. The example plugin does not visit the program.

[jzhan-canva]

I can find this similar issue #1627 and it was resolved by #8867
maybe this maybe_grow_default is needed in rkyv as well?

[jzhan-canva]

I'm able to reproduce this issue in a unit test
