[windows2000] Error code: SIGTRAP

[kenorb]

I've run https://copy.sh/v86/?profile=windows2000

The following snap/crash happens in Chrome browser (version 95.0.4638.69, 64-bit):

Error code: SIGTRAP

Usually it happens when clicking on 'My Computer', then opening 'Local Drive (C:)' and within 1 second before or after icons are showed up. It doesn't happen when DevTools are opened.

I can reproduce this. I also reverted to an older version of v86 (from January this year) and it had the same issue.

When the crash happens chromium writes to stdout:

Setting MAX_PAGES to 1 seems to fix the issue, so it's probably related to some of the existing issues chromium has with big wasm modules.
