Summary: "Allowed memory size" and "bus error" crashes in 7.4

My apologies for not providing clearer instructions for running the tests.
You could copy phpunit.xml.dist to phpunit.xml and change the memory_limit value in there, which the
tests will then use.

Turns out the memory_limit is set in the phpunit.xml.dist, and removing it there does produce a
segfault. There is no useful trace because a corrupted function causes a jump to an invalid address.
Unfortunately there are no warnings under valgrind.

After creating a cfp_test mysql user and database and running "make integration" first, I
now get:
Fatal error: Allowed memory size of 805306368 bytes exhausted at
/home/nikic/php-7.4/Zend/zend_hash.c:2079 (tried to allocate 1048616 bytes) in
/home/nikic/repos/opencfp/vendor/fzaninotto/faker/src/Faker/Provider/Text.php on line 84
I was not able to set memory_limit=-1 to produce the bus error, because the test runner apparently
ignores ini files and options specified on the command line.

Can't reproduce memory limit / bus error, presumably because the test suite does not work
correctly: I get a lot of "RuntimeException: The config file
"/home/nikic/repos/opencfp/config/testing.yml" does not exist" errors.

The command I use to run the integration test suite is:
SYMFONY_DEPRECATIONS_HELPER=disabled CFP_ENV=testing vendor/bin/phpunit --testsuite integration
If I set memory_limit in my phpunit.xml file to be -1, it crashes with a bus error.
gdb has issues on macOS Catalina where it needs to be codesigned and I have tried numerous fixes to
get it to work and have been unsuccessful.

It'd be really helpful if you explained how to run the test suite in there. I also thought you
mentioned memory_limit=-1 and a bus error? The latter comes with segfault usually, which you can
make with gdb: https://bugs.php.net/bugs-generating-backtrace.php
You can run that as:
gdb --args php which phpunit
And then "run" on the gdb prompt
