Re: [Libreoffice-commits] core.git: cid#1455212 Uncaught exception

I guess we'll need to look for a better approach to get rid of those 
annoying Coverity "uncaught exception" warnings (of the category, 
"mechanical static analysis may conclude that this can happen, but human 
analysis concludes that this cannot happen; and if it did, we are 
screwed anyway"---i.e., akin to a "this cannot happen" assert(false) 
placed in the code).  std::make_shared does have benefit over plain 
operator new (potentially bundling the object and the control block in a 
single allocation).
