It is the exit code. When in gdb, the return from notes is -12 as above. By the time It gets back to bash, the lower bytes are dropped so I end up with a 0xFF, which bash thinks is a 0, so the exit code is hidden from view. I tried the !!fn construct in a standard alone test program with no wisdom gained.
