I imagine it's > the bools in "struct M" in runtime.h messing it up, so "struct Note" and > "struct Lock" need __attribute__((aligned(4))) on their key fields. I just did that on gcc-6. The result is: (sid-m68k-sbuild)root@ikarus:/# ./routines Alice Bob Hello World Alice Bob Hello World Alice Bob Hello World Alice Bob Hello World Alice Bob Hello (sid-m68k-sbuild)root@ikarus:/# :D I haven't tested gcc-7 yet, but at least this fix for gcc-6 can be added.
