It's possible there's something wrong with the toolchain, but unlikely as the close-related CC430F5137 is the primary development platform for mspgcc. Most likely you didn't put -mmcu=cc430f6137 on all phases of the build process: if it was missing from the command that produced the final non-relocatable link, the linker wouldn't know the size of the interrupt vector for that part, and would default to a 16-element vector.
