Ramana: I'm sorry, I had trouble parsing your comment (e.g. which option were you referring to by "this" in the final sentence above). What should I configure with when debugging this? e.g. should I keep the --with-abi=aapcs-linux and lose the --with-float=hard? should I be testing with the other options Jakub mentioned? etc. (Sorry about my ignorance here; I'm not particularly familiar with arm, and my test machine is slow which makes it difficult to exhaustively try every possibility).
