No the stripped binary is with the old and new compiler is 60MB. That seems to be the size of my code. So it's not an issue code bloat issue. The binary with debug info goes from 180MB to 1200MB when I upgrade the compiler. I can see the .o files having to do with my MPL generated en/decoder are huge. Does debug information affect performance in any way? Chris
