d676863b64b58bf73a7f26eea70f81aeba517b13)
# gcc -c nine_ff.i -O2 -mavx2
during GIMPLE pass: vect
../mesa-9999/src/gallium/frontends/nine/nine_ff.c: In function
'nine_ff_update':
../mesa-9999/src/gallium/frontends/nine/nine_ff.c:2073:1: internal compiler
error: in operator[], at vec.h:910

Please submit a full bug report, with preprocessed source (by using

-O2 -mavx2 are required to trigger it; -O1 or plain -mavx make it go away.
Thanks!
