This is very unlikely that my patch caused this. The testcase as I can see uses
8-byte vectors and standard arithmetic operations. My patch introduces vector
shuffling on 16-byte vectors. The way the operations from pr23135.c are
performed didn't change.
On x86 linux the testcase does not cause segfaults, so may be you could
investigate via gdb which function cause segfault on cris-elf.
Thanks,
Artem.
