I just tried to compile Suse Linux package ladspa-1.12.code10-56 with the GNU C++ compiler version 4.3 snapshot 20070209.
The compiler said Descriptor.h: In static member function 'static void* Descriptor<T>::_instantiate(const _LADSPA_Descriptor*, ulong) [with T = CabinetII]': Descriptor.h:117: internal compiler error: in vectorizable_type_promotion, at tree-vect-transform.c:2601 Please submit a full bug report, with preprocessed source if appropriate.
