Subject: shape_3rd_derivative* checks for update_3rd_derivatives
X-Git-Tag: v9.2.0-rc1~713^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F9258%2Fhead;p=dealii.git

shape_3rd_derivative* checks for update_3rd_derivatives

The functions shape_3rd_derivative and shape_3rd_derivative_component
check that update_flags contains update_hessians, but they should check
that update_flags contain update_3rd_derivatives. Fix this.
