Description Joel Winarske 2024-03-20 18:41:08 UTC 
In master there is a problem running the libcamera "cam" app on a RISC-V device:

*** stack smashing detected ***: terminated

If I remove the patches in the libcamera recipe, it builds and runs on target without issue.

libcamera bug has the details:

Not an oe-core bug but William, could you take care of it?

@joel, how is cam invoked to reach this issue, I can see one problem which is a segfault which I think I understand and will soon fix it, however, it may not be the problem you are seeing, so I just want to be sure that we can reproduce the problem you are seeing. So please describe the steps to reproduce it.
