That's interesting indeed.
Currently, "plain" is the only value that triggers the issue for me:
Problematic file is the following:
../src/remote/remote_driver.c:790:1: error: stack frame size (2344) exceeds
limit (2048) in 'doRemoteOpen' [-Werror,-Wframe-larger-than]
790 | doRemoteOpen(virConnectPtr conn,
| ^
1 error generated.
Clang version is 19.1.7.
