Hi Soren,
some further information:
- the code is compiled against recent V8 trunk revision,
- using the MS debugger, I traced the crash to this code (factory.cc):
Handle<Struct> Factory::NewStruct(InstanceType type) {
CALL_HEAP_FUNCTION(Heap::AllocateStruct(type), Struct);
}
Additional info provided by the MS Debugger folows:
