Subject: [PATCH] test: wrap binaries using systemd DSOs when running w/ ASan
|
|
|
|
Let's detect & wrap binaries which are linked against systemd DSOs and
|
|
we're running under ASan, since otherwise running such binaries ends
|
|
with:
|
|
|
|
```
|
|
==633==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.
|
|
```
|
|
|
|
