Segmentation fault when executing "procinfo -a"

Dear all,
I got segmentation fault error when I execute "procinfo -a" but not a problem when I just execute procinfo.

How can I troubleshoot the problem?

regards,

Not an easy thing to do

I would suggest using strace to try and get some information about what happens before it crashes (-f tells strace to follow forks):

Code:

strace -f procinfo -a

You might need to install strace first. A good tutorial on how to hunt bugs with strace can be found (see next message, apparently I can't post links in my first post).

hmm, thanks for the reply, I need to organize my time to dig into this though...
I appreciate this...
