Problems generating corefiles with WSL2

[paul-haskell]

Hi all -- I am trying to generate a corefile under WSL2.

1. I disabled apport (sudo service apport stop)
2. I set the kernel.core_pattern appropriately (sudo sysctl kernel.core_pattern=core.%e.%p)
3. I set the corefilesize limit to 'unlimited'
4. I verified the current directory is writable by all
5. I ran a few simple programs that should throw a core (abort(), integer divide-by-0)

...but I never get a core. I do reliably get a corefile on a native Ubuntu machine.

Does anyone have any ideas to try? Thanks!

(I am running WSL version 2.2.4.0 with default Ubuntu i.e. 22.04.3 LTS. I am running Windows version 10.0.22631.4037 .)
