UseAfterReturn Wiki : Enabled By Default in GCC 13 (+ Clang 15)?

[AE1020]

I observed that a program which depended on stack addresses on x86 growing downward stopped working in address sanitizer with GCC 13.

But if I do:

 export ASAN_OPTIONS=detect_stack_use_after_return=0

...then it works.

So it seems that UseAfterReturn is enabled by default in GCC 13. But the wiki says: "AddressSanitizer currently does not attempt to detect these bugs by default, only with an additional flag run-time: ASAN_OPTIONS=detect_stack_use_after_return=1"
