[PATCH] D155520: [LV] Complete load groups and release store groups in presence of dependency

[Anna Thomas via Phabricator via llvm-commits]

anna added a comment.

fixed use-after-free error (with added testcase). This bug wasn't there before the patch because we would break out of the inner loop accessing A, whereas now we were continuing to see which other A accesses needed to release the group.
