Subject: vbo: Fix vbo_split_copy to pass correct max_index to draw.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9a7acbccfbc061322be493633d5c5bf4afd302b5;p=mesa.git

vbo: Fix vbo_split_copy to pass correct max_index to draw.

vbo_split_copy was passing one past the max_index to draw function
which caused _tnl_draw_prims function to read uninitialized values
from copied array.

Bug was spoted in valgrind report of progs/tests/cva_huge.
