Hi everyone.
I've discovered something strange in fetchmail (debian 2.2r4 + 2.2.20):
[20:00](shf(_at_)equinox shf)$ fetchmail a
Segmentation fault
[20:00](shf(_at_)equinox shf)$ gdb `which fetchmail`

fetchmail version is 5.9.3+NTLM+SDPS+SSL+NLS.
I've tested it on slackware 7.1 and 8.0 (both on kernel 2.4.12)
with fetchmail 5.4.0+NLS (7.1) and 5.8.6+SSL+NLS (8.0), and here is the
result:
$ fetchmail a
Enter password for shf(_at_)a: ^C
fetchmail: Caught SIGINT... bailing out.
$
Odd. That's the result I get with my 5.9.5, eg no segfault.

Hoplophobia (n.): The irrational fear of weapons, correctly described by
Freud as "a sign of emotional and sexual immaturity". Hoplophobia, like
homophobia, is a displacement symptom; hoplophobes fear their own
"forbidden" feelings and urges to commit violence. This would be
harmless, except that they project these feelings onto others. The
sequelae of this neurosis include irrational and dangerous behaviors
such as passing "gun-control" laws and trashing the Constitution.
