node -v in bash PROMPT_COMMAND causes assertion error

[isaacs]

Reproduce:

export PROMPT_COMMAND='node -v'
bash

On the first call, it raises this:

Assertion failed: (stream->write_queue_size == 0), function uv__write, file src/unix/stream.c, line 324.

Taking ownership, I'm pretty sure I know what's causing this.

Correction: the PROMPT_COMMAND isn't what causes this. It's due to having . <(npm completion -s) in my .bashrc file.

Also, piping stderr to /dev/null prevents the error.

Steps to reproduce:

// shellout.js
console.log("echo 'foo'")

. <(node shellout.js)

Expect: Echo foo to console

Actual: Assertion failure
