Subject: [PATCH] test: account for ADDR_NO_RANDOMIZE if it's set
|
|
|
8d419f |
|
|
|
8d419f |
On ppc64le sanitizers disable ASLR (i.e. by setting ADDR_NO_RANDOMIZE),
|
|
|
8d419f |
which opinionated_personality() doesn't return. Let's tweak the current
|
|
|
8d419f |
personality ourselves in such cases.
