get_posts ignoring 'category' parameter

[Ton_y]

The get_posts function is returning all posts regardless of what the 'category' parameter is set to.

This is happening using PHP 5.4.19 and WordPress 3.9.1

Another person has complained of the same problem at stackexchange:

WP_Query is affected by this issue as well and it looks like any function that uses get_posts or WP_Query is going to be having problems returning correct results when using the 'cat' or 'category' parameter.

I am unable to reproduce this with a clean WordPress 3.9.1 install, running PHP 5.4.19. I've simply added two posts, of which I placed one in a newly created category (with ID). Then, I ran

$posts = get_posts( array(
	'posts_per_page' => -1,
	'category' => 2
) );

on the init action, after which $posts contained the single post in category 2.

Could you provide a way to reproduce the issue you're encountering?

Steps to reproduce if still a problem - this works for me.
