* Base: account for calloc aborting in security unittestsjln@chromium.org2013-02-151-32/+47
| | | | | | | | | | | | | | On Linux, when not using tcmalloc, we still have a small wrapper that aborts when allocation functions OOM. In that configuration, we now We consider it a successful detection of an overflow condition if the process aborts.

| | | | | | | | | | | | | | Add more compiler barriers to prevent the compiler from optimizing out calls to the very function we're testing. This makes SecurityTest* pass in a Clang release build.

| | | | | | | | | | | | | | | | | | | We loosen ASLR by only growing one random mapping. The previous version had security benefits but had a negative performance impact. This change aims to be performance neutral in respect to the pre-ASLR era. At a later date, we may try to strike a good balance between performance and security.
