Summary0000555: IPOPT with exact hessian fails for leastsq.a4c model
DescriptionIf code/trunk/models/johnpye/leastsq.a4c is modified to contain "OPTION hessian_approximation 'exact';" (actually the default value) then IPOPT crashes with the following output:

PROGRAM FATAL ERROR: ascend/system/relman.c:632:relman_hess: Assertion failed: 0 < i < hess_matrix->dimension (val = 13.000000, low = 0.000000, up = 13.000000)

This crash doesn't occur if the 'limited-memory' (numerical hessian approximation) option is used instead.

This is a serious crash that we need to fix.
