Wondering if it was a 1.7.3 issue, I switched to 1.7.2 which showed exactly the same problem.  Moving back to 1.7.1 clears it.  It looks very much like memory corruption and seems to particularly affect the lower half of displayed images.

Woah, yes I have! I am using GDAL trunk ("1.8.0") to churn through some imagery, and noticed strange black lines through some of the output. In my initial investigation I couldn't find them in the source data. I am glad you posted, because I was going to have to track this down eventually and my large source data makes that a slooooow process.
