Hi Mark,

I can't help you directly myself as I don't know the PVA API, and from
his silence in recent days I suspect Michael is busy (he may be in
Florida). However if you read the release notes for both pvData and
pvAccess (linked from the Base-7.0.1 web-page) they have some summaries
of required application changes which clean up a whole raft of potential
and real memory leaks and other problems.

That said, the error below might just need a 'const' keyword adding to a
declaration somewhere, that is mentioned as one change in the pvAccess
notes.
