Please could you try the patch found in this email (and copied here for ease of access): https://www.sourceware.org/ml/binutils/2015-07/msg00319.html The issue is the the MSP430 has two different sizes for its pointers, depending upon whether large mode has been enabled or not, but the BFD library was assuming that pointers were always 4 bytes long...
