I had this problem for months, and finally was able to reproduce it.
I informed the current maintainer of procps, Chuck Blake <cblake@bbn.com>, and thanks to his wonderful help I let him log into my host this evening and he debugged ps and found & fixed two buglets very quickly. They were truly small -- an off-by-one thing and another buffer size problem. Besides the simple fix to the off-by-one, what he found worked for me in the buffer size problem temporarily was simply to increase the static buffer size a bit. He already mentioned a more perfect fix, so I'm tempted not to reveal the hack that makes it just work until he provides the real true fix; I'm sure he left my copy with the hack just to prove that that was the problem, so he can go back and know what bugs to fix in the real version.
I have a feeling he'll have the fixes out shortly along the regular distribution channels.
BTW, he mentioned the %a option to GNU sprintf as a possible better solution to the static buffer size overflow problem. I was looking for the updated manuals for GNU's sprintf since it wasn't in the manual pages I got on my system. Where do I look up these updated GNU sprintf documentations? (The source code??) How portable would that be? I guess it can't matter much since ps is sort of OS-specific.
Thanks, Bradley Allen <Ulmo@Q.Net>
