Unfortunately they just reveal an ABI issue. I believe there are some fixes coming but given that the issues are a decade old in many cases actually fixing these things must be approach with care so as not to create regressions. >>These commits just introduce a define _FIXME with value of 0, to >>document that the userspace ABI was handled incorrectly long ago. >> >>These commits do not fix anything.
