mem_32 is a field inside a union. The real array is "buffer", and it can
handle the ctx->buffer->mem_32[15]. It is:
buffer_32 buffer[16]; //512bits
I haven't seen this warning on bull GTX card (i wasn't there for a
while, and it was refusing connection when i tried it some time ago).
I expect it to succeed on TS. Have you tried?.
I can change it to something like this: ctx->buffer[15].mem_32[0].
Thanks for testing.
