Are we talking about the same bug? I submitted two close together. #1543 affects the libmudflap build within gcc-4.1.2-final. I don't know if that's soft-float or OABI specific, as I did not try any other configuration. It does not affect gcc-4.2.1. #1542 affects soft-float gcc-4.1.2 only: it needs the same patch as I submitted for 4.2.1 earlier this week (and Ulf applied). Hamish -- Hamish Moffatt VK3SB
