Why does one scipt give an error, when I have a script using #pragma strict?

I had a project that suddenly gave me errors when I started adding #pragma strict to my scripts

I removed the code not giving errors, and ended up with these two scripts:

1) PragmaScript: (yes, this is the entire script)

#pragma scrict

2) ScriptInFolder:

function Start ()
{
    var names : Array = new Array();
    names.Push("John");
    print(0 + names[0]);
}

ScriptInFolder must be in a folder and running on a gameobject. PragmaScript can be placed anywhere.

The runtime error is:

InvalidProgramException: Invalid IL code in ScriptInFolder:Start (): IL_001f: add

Why does this happen? Shouldn't javascript "fix" these things on the fly, even though I use #pragma strict in one script?
