Bug ID: 82407
Summary: [8 Regression][meta-bug] qsort_chk fallout tracking
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Keywords: ice-checking
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: amonakov at gcc dot gnu.org
Depends on: 82381, 82395, 82396, 82397, 82398, 82401
Target Milestone: ---
Checking qsort comparator validity (transitivity and anti-commutativity
properties) reveals some inconsistent comparators. This meta-bug depends on
bugs filed for individual issues.
This is not strictly a gcc-8 regression, issues could have been present for a
long time, they just started causing a non-release-checking ICE.
