Does a Visual Studio debug build contain any personal information?

I'm wondering about privacy and personal information that's contained in the debug files created by Visual Studio.

I have a project that I have compiled for both debug and release, and I have to zip basically the whole directory tree that contains the solution, the source, the pdbs, etc. and make it available.

I'm wondering what type of information will be released by doing this, other than source and binaries obviously.

Thanks!
