Simple Caddyfile crashes after #6997 #7001
Description
After #6997 was merged, Caddy built from the master branch crashes after running
caddy run --config Caddyfilewith the following Caddyfile:
{
skip_install_trust
}(This obviously isn't a useful Caddyfile - it's the result of me paring down something more useful.)
I'll include the console output at the bottom of this message, as it's long.
I'm running macOS 15.4.1 (ARM CPU) and building Caddy with Go 1.24.3 and xcaddy 0.4.4 by running
xcaddy build 320c57291dbe06e00e0759bdb5cbbf0d622e5968There's no crash when building the previous commit:
xcaddy build aa3d20be3ee451af9465470a28937690104e9422Here's the console output mentioned earlier:
