First one was black and second darkish.
However, I tested this again on r480 and got different results.
Some more testing reveals that sometimes it works and sometimes not.
Im suspecting undefined z or w component is leaking into to the tex instruction,
thus causing random behaviour.

I have been able to reproduce this with another program:
"!!ARBfp1.0\n"
"ATTRIB i0 = fragment.color;"
"TEMP t0, t1;"
"MOV t0, i0;"
"TEX result.color, t0, texture[0], 2D;"
"END"
I either get zero visible fragments with this or then it works as expected.
output:

Mesa program:
-------------
0: MOV TEMP[0], INPUT[1];
1: TEX OUTPUT[0], TEMP[0], texture[0], 2D
2: END;
