Error description
On AIX platform during backup-archive client initialization, GSKit makes calls that require AES and SHA CPU acceleration to be enabled. In case AES and SHA CPU acceleration are disabled, the client will crash. Customer/Support Diagnostics: The call stack of the client crash on AIX shows: (dbx) where pthread_kill(??, ??) at 0x900000000535f94 _p_raise(??) at 0x9000000005357e4 raise.raise(??) at 0x900000000039368 abort() at 0x900000000055d64 psunxthr.psTrapHandler(int,int,__sigcontext *)() at 0x100062fe0 .(0x9001000a0c7621c, 0x100, 0x110300630) at 0x9000000033eb154 aes_init_key(??, ??, ??, ??) at 0x9000000033e7d78 ...

Problem conclusion
Before the fix, dsmc might get a core dump at startup inside the GSKit library on AIX LPAR with the processor compatibility mode set to Power7 while running on Power 8 underlying hardware. After the fix, dsmc will run fine in such an AIX LPAR environment.
