[PATCH] D71780: [msan] Check qsort input.

[Evgenii Stepanov via Phabricator via llvm-commits]

eugenis added a comment.

CompareOptionRecords checks that there are no duplicate options in the sorting comparator function.
I believe this is wrong, because I could not find a promise in POSIX nor in linux manpages that the comparator would never be called with the same object on both left and right hand side.

Nevertheless, I don't want sanitizers to enforce this peculiarity in the standard.
