OK, then it's actually a bug. One important thing to know is that the natural alignment on m68k is actually 16 bits and not 32 bits which causes quite some issues with various upstream projects. We're currently planning on switching the alignment on m68k to 32 bits and chances are that this could this issue as well. Can you maybe try passing "-malign-int" to CFLAGS/CXXFLAGS when building OCaml on m68k to verify this hypothesis? Please note that this also breaks the SysV ABI, so it's not possible to easily do this on a per-package basis. Adrian -- .''`.
