I tried it, with debugging symbols in place (nice!)... I'm still
learning about gdb.
It had a back trace similar to this (abbreviated):
#0 0x0 in ?? ()
#1 0x127901 in ()
#2 0x17dafe in vsscanf ()
#3 0x17b8cf in sscanf ()
#4 0x806332c in parse_proc_status (S=0xbffffabc "Name:\tinit\nState
[..snip!...] ..." P=0xbffffdb58) at ps.c:87
#5 [...snip!...] ps.c:150
#6 [...snip!...] applets.c:96
#7 [...snip!...] busybox.c:100
I also took a look at tinyps (the current ps implementation); it
doesn't have debugging symbols but it too failed in sscanf/vsscanf. I
looked at the call for sscanf, and nothing seems out of place. Here
is what is reported for the data:
P = (proc_t *) 0xbffffd58
*P = { cmd = \000 (15x), ruid = 134656002, rgid = -1073742125, pid =
134689808, ppid = 72, state = 12 '\f' }
I suspect the glibc libraries would be Debian's last glibc 2.1.3
security update; should I be using a different version?
