It seems Yusuke's trouble.  Do you compile gcc yourself?

The CI doesn't relate the problem.
I can build fiddle without CI on Debian GNU/Linux (lenny).
The backtrace in [ruby-dev:41214] is such case.

gcc -v may help you.
It shows the include path.
Debian gcc has /usr/include/i486-linux-gnu in the include path.
So it can find ffi.h in the directory.
