Hi Siva Prasad
Thanks a lot for your quick response.
This is a sample c code that i ve posted here. Actually we have 100k LOC of
such code in our application.
and we have so many such uninitialized variable in that code.
But this is code was working fine in AIX server and we ported and compiled
the same in HP we meet with Memory Fault error.
Do you have any solution for this?
Thanks.
