I found it traces to: // Return a special value to indicate that the process received an = unhandled // signal during execution as opposed to failing to execute. WaitResult.ReturnCode =3D -2; in /usr/src/contrib/llvm/lib/Support/Unix/Program.inc . (I did the trace between that and main by inspection but I'll not list the details here.) -2 treated as an unsigned-byte is 254 for the rpi3 (and most common FreeBSD machines [all?]). =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
