segmentation fault in WCS

I was going thru the WCS and started to have segmentation faults and everything was crashing,
finally I discovered the problem

The RESX and RESY are postive numbers, despite sometimes RESY being given as a negative value.

The funny thing was the PID was crashing and the sript was sending a ows.php reply, even more funny is that wcs_resolution is given with Y as negative value, at least in all the examples that I saw

Also I read the documentation and it says that BBOX is required, well actually not !!! without the BBOX it will reply with all the layer.
