# This test could fail if the testing package does not wait until
# a panicking test does the panic. Turn off multithreading and GC
# to increase the probability of such a failure.
env GOMAXPROCS=1

# If the test exits with 'no tests to run', it means the testing package
# implementation is incorrect and does not wait until a test panic.
# If the test exits with '(?s)panic: die.*panic: die', it means
# the testing package did an extra panic for a panicking test.
