Happens on every arch I have access to, I'm trying to find out a solution. The
thing is when I run it from strace It doesn't segfault. Will you please test it ?

---8<---
$ strace procmail
[LOT OF OUTPUT]
Ctrl-C
---8<---

And see if it segfaults, It doesn't for me

Cheers,
Ferdy

strace procmail :

rt_sigaction(SIGALRM, {0x40a5e0, [ALRM], SA_RESTORER|SA_RESTART, 0x2aaaaaf90a70}, {SIG_DFL}, 8) 
= 0
read(0,  <unfinished ...>
procmail: Terminating prematurely

and then check your dmesg.. :

procmail[13941]: segfault at 0000000000000000 rip 000000000040f29b rsp 00007fffffca9790 error 4

, on x86 gentoo (32 bits) procmail doesnt segfault when doing ctrl c

Erik

Can you post your emerge info on the machine that doesn't segfault ? Because
I'm
also getting segfaults on my Athlon-XP

Ferdy

procmail ctrl c
procmail: Terminating prematurely
Segmentation fault

But there is no segfault in  > dmesg

procmail-3.22-r7 commited to the tree with a fix for this bug. It will touch
the
mirrors in a couple of hours.
