At least one of them I have resolved with the attached patch. First testcase failure: test-ffi (fixed by my patch). The guile code appar= ently assumes that sizeof(ffi_arg)<=3Dsizeof(void **). This is a faulty as= sumption; it holds on *most* platforms, but with the mips64 n32 ABI, sizeof= (void **)=3D=3D4, and sizeof(ffi_arg)=3D=3D8. So every foreign function th= at returns a pointer is liable to corrupt data, and anyone retrieving the r= eturn value as a simple void * is only going to get sign-extension garbage = on big-endian (usually NULL). Second testcase failure: check-guile fails due to 'ERROR: foreign.test: pro= cedure->pointer: qsort - arguments: ((null-pointer-error "pointer->bytevect= or" "null pointer dereference" () ()))'. I strongly suspect it's related t= o the ffi_arg issue mentioned above, but I'm still peeling away macro uglin= ess to track it down. If anyone wants to pitch in with additional guidance= or patchwork, I'd be happy to listen and test. (The patch applies against 2.0.11 release or against current HEAD, where it= also fixes the new testcases for test-foreign-object-scm and test-foreign-= object-c.
