I can't reproduce this with the current -mm lineup. I compiled up a 32-bit app on x86 and transferred that across. Maybe it got fixed. Please test 2.6.13-mm2, which appears to be an hour or two away. If it still fails then I'd need a recipe (including URLs and stuff) with which to reproduce it please.
