SIGINT throws bats into endless loop on Bash 5.2 (RC)

[gioele]

Describe the bug

In versions 1.8.0, test "73 CTRL-C aborts and fails the current test" hangs when run on a recent Debian sid system.

Test 73 gets stuck without producing any output. Killing the test with CTRL-C makes the test suit starting the abort procedure, but then the test process gets stuck in Running state. Sending SIGKILL to the test process unblocks the test suite abort procedure.

ok 71 Parallel mode works on MacOS with over subscription (issue #433)
ok 72 Failure in free code (see #399)
[nothing shown on the terminal; the test process spins using 100% CPU until CTRL-C is pressed]
^Cnot ok 73 CTRL-C aborts and fails the current test
# (in test file test/bats.bats, line 767)
#   `wait $SUBPROCESS_PID && return 1' failed with status 130

# Received SIGINT, aborting ...

^C^C^C^C^C^C^C^C^C^C^C^C# bats warning: Executed 73 instead of expected 274 tests

To Reproduce

Steps to reproduce the behavior:

1. docker run --rm -it -v /tmp/d debian:sid
2. apt update && apt install git
3. cd /tmp && git clone https://github.com/bats-core/bats-core && cd bats-core
4. mkdir -p ~/.parallel && touch ~/.parallel/will-cite
5. bin/bats --tap test

Expected behavior

Test 73 should run successfully.

Environment (please complete the following information):

• Bats Version 1.8.0
• OS: Debian sid
• Bash version: 5.2.0(1)-rc2

Thanks for the report. This works with a previous Bats version?

This happens also in version 1.7.0, but there the test number is 79.

ok 78 Failure in free code (see #399)
^Cnot ok 79 CTRL-C aborts and fails the current test
# (in test file test/bats.bats, line 833)
#   `wait $SUBPROCESS_PID && return 1' failed with status 130

# Received SIGINT, aborting ...

I was able to reproduce this with the bash:rc Docker Image, which provides Bash 5.2.
