# pppd dump
Segmentation fault
# pppd /dev/ttyS0 dump
pppd options in effect:
dump            # (from command line)
/dev/ttyS0              # (from command line)
lock            # (from /etc/ppp/options)
Segmentation fault
# cat /etc/ppp/options 
lock
# uname -a
Linux XXXXXX 2.4.18-alt8-up #1 Thu Aug 22 20:57:21 MSD 2002 i686 unknown unknown GNU/Linux

The dryrun option causes segfault too.

Reproducible with ppp-2.4.1-alt8 (from Sisyphus) and ppp-2.4.1-alt6 (from ALT Linux Master 2.0).

бага подтверждается.
С другой стороны есть утилита pppdump

pppdump не имеет отношения к данному вопросу - это утилита для разборки файлов от опции record, а pppd dump должен выдать установленные значения параметров конфигурации (что он и начал делать во втором случае, но ве равно упал).
