Re: [patch #PR 25933] memory leaks

[Uttam Pawar <uttamp at us dot ibm dot com>]

This is a modified patch with all the changes suggested by Ian. I hope this is in right 
format now. Compiler has been bootstrapped ok on powerpc64-linux and the test results show 
no new regressions.

Thanks in advance for reviewing it.
