This is extremely wierd!

So it looks like something is affected by the optimization level. Usually, it is an uninitialized variable, buffer overflow, strict aliasing issue, or maybe a GCC bug...

Since it is unlikely that this specific bug is in the standard GCC sources (other people would have noticed), maybe it could be somewhere in the C sources added for your NeXT configuration?
