 Hi Harald, thank you for having shared your point of view.

 I agree that POSIX specs are important but not mandatory.
 Moreover they not always very specific like in this case.

 Obviously for the functions defined elsewhere it might be different.
 I prepared a test but feel free to improve it. Here the results:

roberto at vm-ubuntu18:~/tinycore-editor/busybox$ src/busybox ash ./test2.sh
ash: using fallback suid method
ciao! at line 29 == 29
hello at line 22 == 22
ERROR: test2.sh failed at line 23, rc: 1
onerror() at line 16 == 16
mytest should have failed at line 23
pippo
ERROR: test2.sh failed at line 34, rc: 1
onerror() at line 16 == 16
exit at line 34 == 34 with pippo but not pluto
