Description Jim Meyering 2008-01-17 09:08:06 EST
Description of problem: with an existing leases file, dhclient always segfaults

Version-Release number of selected component (if applicable):dhclient-4.0.0-3.fc9

How reproducible: run "ifup eth0", which runs
e.g., dhclient -1 -q -lf /var/lib/dhclient/dhclient-eth0.leases -pf
/var/run/dhclient-eth0.pid eth0

Steps to Reproduce:
Actual results:
Program received signal SIGSEGV, Segmentation fault.
0x000000000041b832 in get_char (cfile=0x68ce40) at conflex.c:185
185                     c = cfile->inbuf [cfile->bufix];

Expected results:
"ifup eth0" would succeed

Additional info: work-around: remove the leases file,
or apply the attached patch.
