Expected Behavior

Upon pressing Ctrl-C program should exit and coverage information should be generated.

Observed Behavior

npm start

> start
> nyc node index.js

Server running at http://127.0.0.1:3000/
^Cnode:internal/validators:95
      throw new ERR_INVALID_ARG_TYPE(name, 'number', value);
      ^

Node.js v20.8.1

Troubleshooting steps

• Does not happen in Node v18.
• Does not happen if just running server node index.js without nyc

Any updates on this? Is this accepted as a pretty severe bug now that Node.js 20 is the current active release?

[SSANSH]

maybe the main solution will be to bump from foreground-child 2.0.0 to latest version. issue is duplicated here sometimes dead loop · Issue #54 · tapjs/foreground-child · GitHub

[nwalters512]

I also witnessed this on Node 20, indeed it seems to be an issue with foreground-child incorrectly treating a string as a number. There are a few options for a fix; I asked the maintainer which he'd prefer: tapjs/foreground-child#54 (comment)

[nwalters512]

Turns out this is already fixed in the latest version of foreground-child. I opened #1546 to upgrade the package.

Another reproduction:

npm install nyc@15.1.0 segfault-handler
npx nyc -- node -e 'require("segfault-handler").causeSegfault()'
