This sounds like issues that have been dealt with on the development branch 'jperraud'; certainly the leakages with character vectors. You may want to work from that branch; it looks like you have no problem starting from source code.
I know there is a now pressing need for an updated release, but I have to go through enough testing. Also, some steps of the release I cannot perform myself.
