Memory leaks - patch2

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

Hi,

The following patch fixes some more memory leaks. I did not file any PRs
to track these leaks (so these are not reported). Let me know if I need
to open one.

Bootstrapped and regtested on powerpc64-linux. No new regressions.

Thanks,

Uttam
