I'm sure this is a simple question but would anybody be able to point out to me why the following generates overfull \hbox errors for the two \colchunk macros? It doesn't appear LaTeX needs to do any line breaking at all.



movzx ebx, cx
push ebx
call someFunc

mov ecx, edx

Depending on your usage, you can issue \par at the beginning of \colchunk, which takes care of the "Overfull \hbox warnings." You may have to adjust the vertical alignment then. However, there are other ways of performing this parcolumns approach that doesn't require such a fix. You could also use \linewidth for your minipage, which is marginally larger than .45\textwidth (by about 12.65pt). – Werner Dec 31 '11 at 17:14
[Unrelated to your question] the parcolumns package allows you to form columns that can break across pages. Putting the content of a colchunk in a minipage negates this. – cmhughes Dec 31 '11 at 17:55

Use the option nofirstindent for the environment parcolumns. More information are given in the documentation
