Sorry, I now tested the patch. It looked good to my untrained eyes,
but upon testing it on columns:
...
personality(PER_LINUX) = 4194304
geteuid() = 1000
getuid() = 1000
getgid() = 1002
getegid() = 1002
brk(0x8054098) = 0x922d000
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
...it should have said -EINVAL or something like that.
