Hi, I've finally got around to this, and after some investigation implemented it using the static constant facility in cmpwt.lsp instead: http://github.com/angavrilov/ecl-sse/commit/cb0efd01987c4dead7a94f8dc23ef8ee26353e9c However, I see that this facility is completely disabled on MSVC. Do you remember what the actual problems with it were, and is it perhaps possible to disable only specific types that are broken instead of everything? Also, is it documented somewhere what aligment guarantees does Boehm GC provide? It would be very good if the 32-byte objects of the sse_pack type could be guaranteed to be 16-byte aligned (actually, the current code might crash if that is not true). Using static constants here has a nice property that the C compiler automatically ensures proper alignment.
