I've traced it in gdb, and I saw a function (called via an inline) being given valid arguments but receiving junk arguments. It looks like the stack pointer got messed up (I didn't check, I was viewing source not asm at the time). Calling the function directly, rather than through the inline (which only added an argument to the argument list) worked fine. Having your arguments corrupted during a function call sure looks like a compiler bug to me. -- Sean Burford x34135 ITS Systems Specialist Adelaide University
