Why am I getting this error when I try to open a file with DDD?

Debugger: DDD.

64-bit Ubuntu Precise Pangolin system.

Whenever I try to open a very simple C program in ddd, I get the following error:

Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
Warning: Cannot convert string "%s" to type %s
Warning: Could not load font "-*-lucidatypewriter-medium-*-*-*-*-120-*-*-*-*-iso8859-*", using font "fixed" instead
Warning: Could not load font "-*-lucidatypewriter-medium-r-*-*-*-120-*-*-*-*-iso8859-*", using font "fixed" instead

Also, ddd opens fine after all these errors show up in the terminal, but without the source file that I want to debug. I cannot find a solution for this online! Thank you.

EDIT:

I am getting the above error when running as root. When working with a normal user, I get the following:

I think I figured it out with @Fredrik's help.

The UTF-8 incompatibility seems to be a longstanding bug in ddd. A lot of people have reported this, but no one seems to have fixed it.



The reason my code was not showing up in ddd was because I didn't use the parameter when compiling -g

.
