Thanks , valdemar.
After export and restart process operation, 'pargs -e pid' contains the env which I \
am expecting.
What does it mean 'no mapping for address' ?
envp[8]: LD_PRELOAD=libumem.so.1
....
envp[31]: UMEM_DEBUG=default,verbose
envp[32]: UMEM_LOGGING=transaction
and ::findleak could print some location and its call stack .
