[Bug report] Crash on trying to debug with LLDB

[skittishdev]

Hello,

I'm trying to use this framework for a C project on MacOS. When I run the tests without trying to debug, they execute as expected. But when I try to start a debugger, I am seeing a crash with a backtrace that asks to submit a bug report.

I'm using criterion-v2.4.2. I started lldb like so: sudo lldb <path/to/executable>

(lldb) run --debug
Process 28941 launched: '/Users/crk/Developer/ws-shoshin-c/ds/linked_list/build/tests/test_alloc_and_free' (arm64)
[----] Criterion v2.4.2
[====] Running 2 tests from CreateLinkedList:
PLEASE submit a bug report to  and include the crash backtrace.

I was able to use the debugger leveraging the manual instructions provided here: #420

I also tried explicitly specifying run --debug=lldb (and I have lldb-server on my path). But that results in an error as well.
