Well, you've improved things, but you're still missing the "Pass 4" 
output line.

As to what we *can* see, something odd is going on.  BASIC1 just tests 
that the first compile of a script isn't cached.  So far so good in your 
  output.  BASIC2 compiles the same script, expecting it to be cached. 
Yours wasn't (since the Pass 3 line didn't say "using cached").

Let's try some simple tests by hand.  Here's what I get when I compile 
the same simple script twice:

# stap -v -p4 -e 'probe begin { log("hello") }'
Pass 1: parsed user script and 54 library script(s) in 
520usr/20sys/542real ms.
Pass 2: analyzed script: 1 probe(s), 1 function(s), 0 embed(s), 0 
global(s) in 10usr/0sys/11real ms.
Pass 3: translated to C into 
"/tmp/stapHTajTu/stap_18fff0808dbc7fac961586069aa96877_233.c" in 
0usr/0sys/1real ms.
/home/dsmith/.systemtap/cache/18/stap_18fff0808dbc7fac961586069aa96877_233.ko
Pass 4: compiled C into "stap_18fff0808dbc7fac961586069aa96877_233.ko" 
in 3090usr/810sys/3770real ms.
# stap -v -p4 -e 'probe begin { log("hello") }'
Pass 1: parsed user script and 54 library script(s) in 
510usr/20sys/536real ms.
Pass 2: analyzed script: 1 probe(s), 1 function(s), 0 embed(s), 0 
global(s) in 10usr/0sys/11real ms.
/home/dsmith/.systemtap/cache/18/stap_18fff0808dbc7fac961586069aa96877_233.ko
