I agree with @coleenp that AIX seems to still use the data segment and sbrk for dynamic memory allocation. I am not sure about memory sticking to the process.

With these changes I see several of the gtests failing on AIX.


[==========] 58 tests from 6 test cases ran. (3718 ms total)

[  FAILED  ] os.safefetchN_negative_vm

[  FAILED  ] os.safefetch32_negative_current_null_vm
[  FAILED  ] os.safefetch_negative_at_safepoint_vm


I can experiment with the disclaim option as well.
