Bug ID: 103453
Summary: ASAN detection with clang
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: glisse at gcc dot gnu.org
Target Milestone: ---
Libstdc++ uses __SANITIZE_ADDRESS__ to detect if ASAN is enabled, but with
clang that should be __has_feature(address_sanitizer). This means that
_GLIBCXX_SANITIZE_STD_ALLOCATOR is not automatically defined, and thus defining
_GLIBCXX_SANITIZE_VECTOR has no effect.
