The current git version of bash (at least on x86_64-apple-darwin18.7.0)
gives a spurious warning about a recursive trap invocation when running
the following more than once on an interactive shell. The trap unsets
itself before resending the signal, so there should be no recursive
invocation.
bash-5.0$ echo $BASH_VERSION
5.0.11(1)-maint
bash-5.0$ trap 'echo int; trap - INT; kill -s INT $$' INT; kill -s INT $$
int
bash-5.0$ trap 'echo int; trap - INT; kill -s INT $$' INT; kill -s INT $$
bash: warning: run_pending_traps: recursive invocation while running
trap for signal 2
int
bash-5.0$ trap 'echo int; trap - INT; kill -s INT $$' INT; kill -s INT $$
bash: warning: run_pending_traps: recursive invocation while running
trap for signal 2
int
Thanks and happy new year,
