8d22ab0e503ccaa464cbecd94d1059dbc5a61f4a ci: Enable address sanitizer (ASan) stack-use-after-return checking (practicalswift)
Pull request description:
Enable address sanitizer (ASan) stack-use-after-return checking (`detect_stack_use_after_return=1`).
Example:
```
#include <iostream>
#include <string>
const std::string& get_string(int i) {
return std::to_string(i);
}
int main() {
std::cout << get_string(41) << "\n";
}
```
Without address sanitizer (ASan) stack-use-after-return checking:
```
$ ./stack-use-after-return
$
```
With address sanitizer (ASan) stack-use-after-return checking:
```
$ ASAN_OPTIONS="detect_stack_use_after_return=1" ./stack-use-after-return

ci scripts
This directory contains scripts for each build step in each build stage.
Currently three stages lint, extended_lint and test are defined. Each stage has its own lifecycle, similar to the
Travis CI lifecycle. Every script in here is named
and numbered according to which stage and lifecycle step it belongs to.
Running a stage locally
To allow for a wide range of tested environments, but also ensure reproducibility to some extent, the test stage
requires docker to be installed. To install all requirements on Ubuntu, run
sudo apt install docker.io ccache bash git
To run the default test stage,
./ci/test_run_all.sh
To run the test stage with a specific configuration,
FILE_ENV="./ci/test/00_setup_env_arm.sh" ./ci/test_run_all.sh
Be aware that the tests will be build and run in-place, so please run at your own risk. If the repository is not a fresh git clone, you might have to clean files from previous builds or test runs first.
