Hello, after quite some debugging the failure in DEC2BIN() function in the CppunitTest_sc_addin_functions_test on ppc64le we have confirmed that the UNO bridge isn't fully ABI compliant. For example int32 parameters are not correctly sign-extended to 64-bit values. Please see https://bugzilla.redhat.com/show_bug.cgi?id=2237384 for all the details. With regards, Dan
