Segmentation fault on output executable

[OvercookedBeef]

I was following the instructions for SEA from here.

Here are my steps:

$ node --experimental-sea-config sea-config.json
Wrote single executable preparation blob to sea-prep.blob
$ cp $(command -v node) "sea_linux"
$ npx postject "sea_linux" NODE_SEA_BLOB sea-prep.blob --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2
Start injection of NODE_SEA_BLOB in sea_linux...
warning: Can't find string offset for section name '.note'
💉 Injection done!
$ ./sea_linux 
Segmentation fault (core dumped)

Here's my sea-config.json:

{
    "main": "index.js",
    "output": "sea-prep.blob"
}

I ran it with GDB and here's the output, not sure if it's helpful:

Program received signal SIGSEGV, Segmentation fault.

Looks like the same issues as what this person had: #76 (comment)

I'm also on Arch linux.

I tried using the node executable from the official site (nodejs.org) and that one worked. It seems to be something specific to the Arch Linux package (maybe due to the strip): #90

file on nodejs.org's node:

My situation looks related, collector is a Nodejs SEA:

Stripping runs as a part of packing RPM on Rocky Linux but I believe RHEL would behave the same.
