Hello Christian, I will try your suggestion this evening. Also, I 
noticed that I replied to Vladimir this morning instead of the list. The 
version of gcc that I am using is 3.2.3 (Debian). I can try upgrading 
this to whatever debian unstable is now at. I can also just leave the 
current version to test any fixes for this issue. Thanks. -Garett
