Subject: ARB prog parser: Release old program string in _mesa_parse_arb_{fragment,vertex}_program
X-Git-Tag: 062012170305~15905^2~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d8e256f9236d3e9dfd433c3a59718f0fdf1ca79a;p=profile%2Fivi%2Fmesa.git

ARB prog parser: Release old program string in _mesa_parse_arb_{fragment,vertex}_program

The program structure passed to _mesa_parse_arb_program is just a
place holder.  The stings that actually need to be released are only
known to the functions calling _mesa_parse_arb_program, so they should
be freed there.
