I tried it with R14B04 also, and it still doesn't work for me. I'll try a few more things to try and discover what it might be. I'm a bit surprised this can even happen in the first place, though.<br><br><div class="gmail_quote">

I should specify this problem is something I noticed when using distributed tests based on ct_slave; I would suspect that local tests being run from a shell started manually do not suffer from this.<div><div>

<div>I've recently discovered that Common Test appears to not be starting basic applications such as kernel and stdlib, but it still starts things like application controllers and whatnot.<br></div><div><br></div><div>
This gives me a few problems because it breaks a few behaviours such as application:which_applications(), being able to start a few applications (they depend on stdlib and kernel. Sstdlib depends on kernel, and manually starting kernel fails because a bunch of processes already have that name). </div>
<div><br></div><div>It will also play negatively with things like manually calling application:set_env/3 before starting an application to configure it (after loading it) as just starting it will overwrite all values, etc. </div>
