It’s probably worth specifying a version, otherwise it will default to the most compatible version.  For ARM, you’ll probably want to use -fobjc-runtime=gnustep-1.8.  Let me know if that makes a difference.

Does this only occur when you’re using LTO?  I seem to recall that we were not emitting sufficient alignment information on some of the structs, which occasionally meant that the linker would align them incorrectly, but I thought that was fixed...
