Bug ID: 17064
Summary: [ASan] Turn use-after-return checking on by default
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: -New Bugs
Assignee: [email protected]

Classification: Unclassified
Filing this as a tracking bug to track progress on turning ASan's
use-after-return checking on by default.
The reason I want this on by default is that there is very little to indicate
to a user that a bug in their code is related to use-after-return, and so it
seems especially valuable to eagerly diagnose it. Also, it seems likely that by
applying LLVM's capture analysis to the instrumentation the overhead associated
with this mode could be significantly reduced.
