malformed header from script

[eworm-de]

Updating to version 2.4.3 I now get internal server error:

[core:error] [pid 59478:tid 59488] [client 127.0.0.1:52110] malformed header from script 'cqrlogo.fcgi': Bad header: \x89PNG

The executable is cqrlogo, which should generate perfectly fine data.

A git bisect points to 3a29b21 being the first bad commit. Reverting that on on top of the release fixes the issue.

The commit message does not give hint on why that change was made. I guess it was supposed to silence a warning (like "warning: this statement may fall through") but at the same time broke the logic?

BTW, for an expect fall though you can add a comment to give the compiler a hint and properly acknowledge the warning:

/* fall through */

Also reverted for Arch Linux package:
