Thanks for quick response, Simon. I have sent a patch to fix this,
please check the patch v2 with subject 'purgatory: do not enable
vectorization automatically for purgatory compiling'.
I tested on machine where the issue can stably reproduced, and can
confirm adding -fno-tree-vectorize to compiling options of purgatory can
fix the issue.
Dave, please check if it is expected from you.
