Hi Anthony, This trivial patch fixes: https://github.com/atgreen/libffi/issues/141 By adding a .note.GNU-stack note to the bottom of src/aarch64/sysv.S. Tested native on aarch64-none-linux-gnu, with no issues in the testsuite. Could you please apply this to HEAD? Thanks, James --- 2014-11-13 James Greenhalgh * aarch64/sysv.S: Add .note.GNU-stack.
