Many buffered tests are failing on master

[rolfv]

This problem is in master only and I tracked it down to this commit using git bisect.

[rvandevaart@drossetti-ivy5 ompi-master-rolfv]$ git bisect good

[720fa860eee7df4f06eb5604058da57453e88b46]   changing the destruct function of list release API to release list items   caused a bug in oshmem application. Fixing the bug with this patch
[rvandevaart@drossetti-ivy5 ompi-master-rolfv]$ 

Although I cannot quite figure out what that commit is when I look at the log. In any event, the errors can be seen on many different buffered send tests.

Looks like this was originally authored by @rppendya

[hppritcha]

Thanks for catching this.

[rhc54]

See #1066

[rolfv]

These errors are now gone so I will close this issue. I believe @rhc54 fixed this with #1066.
