Details

I'm trying to embed node on Windows, however when I run the exe, it crashes with a C0000005 exit code.

Any clues?

Node.js version

17.6.1 from https://github.com/nodejs/node/tree/v17.x-staging Linked against node.lib generated by the build

Example code

from the embedding example https://github.com/nodejs/node/blob/v17.x-staging/test/embedding/embedtest.cc

#include "node.h"
#include "uv.h"
#include <assert.h>

I used the debugger, and I found that it crashes at

int exit_code = node::InitializeNodeWithArgs(&args, &exec_args, &errors);

with Exception 0xc0000005 encountered at address 0x51dfefe: User-mode data execution prevention (DEP) violation at location 0x051dfefe

-858993460 gets stored in exit_code, but I don't know what this means..

[useman]

Found solution, just compile node with shared flag in my case it works .\vcbuild debug vs2022 dll x64 .\vcbuild release vs2022 dll x64
