I am using package strucchange, and encounters the following:

>  bp <- breakpoints(diesel90  ~ regress -1, h=NULL)
Error in La.chol2inv(x, size) : element (14, 14) is zero, so the 
inverse cannot be computed

The obvious problems have been checked, that is, the model matrix is 
of full rank. What can be causing this?

I can send some data if that can be of help.
