hi.
starting from lftp-3.3.0, I have started getting segfaults randomly.
I have lftp-3.3.1 (./configure --without-gnutls --without-openssl),
Fedora's glibc-2.3.90-14, gcc-4.0.2 (generating code for pentiumpro,
lftp compiled with -O0 -ggdb3).
I did "get slang-1.4.9-21.src.rpm", then ^Z, then "jobs" a couple of times.
lftp www.nic.funet.fi:/pub/mirrors/ftp.redhat.com/redhat/linux/rawhide/SRPMS>
