runsc unable to run bash from a guix pack

Description

I'm trying to use runsc to run a software bundle built by guix pack. While it works if i use /bin/sleep 100 as the command, runsc fails immediately if i use /bin/bash -c "sleep 100" as the command. I first encountered this behavior using podman(where I verified that bash from the pack works with runc and only fails with runsc), but I've since reproduced this using just runsc I've supplied the steps to reproduce and attached the logs below. I'm running guix on a Debian 12 box. Please feel free to close if this is not a supported config or if it's not worth investigating. The first error in the log is this line:

Unhandled user fault: addr=7ee9f3a6e025 ip=7ee9f3a6e025 access=r-x sig=11 err=bad address
