- o Minor features (bug-finding):
- - Tor now builds with -ftrapv by default on compilers that support it.
- This option detects signed integer overflow, and turns it into a
- hard-failure. We do not apply this option to code that needs to run
- in constant time to avoid side-channels; instead, we use -fwrapv.
- Closes ticket 17983.
- - When --enable-expensive-hardening is selected, stop applying the clang/gcc
- sanitizers to code that needs to run in constant-time to avoid side
- channels: although we are aware of no introduced side-channels, we
- are not able to prove that this is safe. Related to ticket 17983.
