Compile part 1 (inf.c for inferior) clang -g -o inf inf.c Compile part 2 (sup.c for superior) clang -g -o sup sup.c In one terminal ./inf In a second terminal ./sup {paste the two args printed out by inf} On FreeBSD 14.2 amd64 (different registers) and 14.3 aarch64 I get "in get out of jail! got out of jail!" On FreeBSD 15.0-ALPHA4 I get "Assertion failed: (arg =3D=3D 0x8BADF00D), function get_out_of_jail, file = inf.c, line 10."
