Segmentation fault in GetDP 2.11.0 64-bit Windows

Working with the enclosed files, the command getdp 2D_eucard_v3.pro -pre ResolutionH -msh 2D_eucard_v3.msh behaves differently between the 32 and 64-bit versions of the GetDP 2.11.0 Windows executable. With the 32-bit version, the command works fine whereas with the 64-bit executable it generates a segmentation fault.

The error seems to happen while executing

GlobalQuantity_P = (struct GlobalQuantity*)
  List_Pointer(QuantityStorage_P->FunctionSpace->GlobalQuantity,
  *(int*) List_Pointer(DefineQuantity_P->IndexInFunctionSpace,0)

in file Kernel/Treatment_Formulation.cpp around line 669. In the 64-bit Windows version, the pointer to QuantityStorage_P->FunctionSpace is invalid (0xFFFFFFFF00000001) while it was ok in the 32-bit version. I figured the problem could be circumvented by increasing NBR_MAX_BASISFUNCTIONS in Interface/ProData.h.
