Looks like an issue passing the rType argument of

> #12 (anonymous namespace)::ProxyRoot::queryAggregation(com::sun::star::uno::Type const&) (this=0x2fe7f90, rType=<optimized out>) at stoc/source/proxy_factory/proxyfac.cxx:308

through the binary UNO bridge to the aType argument of

Maybe an issue with calling conventions and the assembly code at

And if there is a general issue with parameter passing through the 
binary UNO bridge, that would most probably also be the reason for your 
first crash at
