rpmalloc and USD
Description of Issue
I am using rpmalloc in my project as a global new/delete override internal implementation for them and although most of the USD functionality is fine across DLL boundaries, I notice that the following class causes problem:
pxr::UsdPrimCompositionQuery query(i_prim, filter);
It seems to allocate in the constructor using std::make_shared and when the instance of the composition query goes out of scope it tries to de-allocate something inside the query (I presume it's the "_expandedPrimIndex"?) and the de-allocation goes through my rpmalloc path. So it seems that the allocation and de-allocation paths don't match.
I don't know if this is just local to me, is it possible to reproduce it at all?
Steps to Reproduce
- Use the DLL version of USD and in your project which uses rpmalloc (or equivalent probably) and allocate a new UsdPrimCompositionQuery. My function looks like this:
std::vectorstd::string UsdHelper::GetExternalReferencesOrPayloads(pxr::UsdPrim const& i_prim) { std::vectorstd::string filenames; // Setup a composition query to search for references or payloads. pxr::UsdPrimCompositionQuery::Filter filter; filter.arcTypeFilter = pxr::UsdPrimCompositionQuery::ArcTypeFilter::ReferenceOrPayload; filter.dependencyTypeFilter = pxr::UsdPrimCompositionQuery::DependencyTypeFilter::Direct;
pxr::UsdPrimCompositionQuery query(i_prim, filter);
auto arcs = query.GetCompositionArcs();
... do something with the arcs ...
return filenames;
}
