Description Masaki MURANAKA 2013-11-01 13:51:12 UTC 
In etc2_rgb8_fetch_texel().
In case block->is_planar_mode == true and punchthrough_alpha == false, dst[3] will not be initialized.

I found it on reviewing texcompress_etc.c (git hash: 0c883e46d871).
Comment 1 Tapani Pälli 2017-09-25 07:42:51 UTC 
I believe it still works correctly because dst[3] is set after etc2_rgb8_fetch_texel using etc2_alpha8_fetch_texel. I'm resolving this as WORKSFORME. Please reopen if there is a failing usecase with the format.
