Peculiar problem with kmail on AMD64 current
I have run into a peculiar problem with kmail where it performs fine on one
AMD64 system and yet the same kernel/userland/packages on other AMD64
hardware results in kmail crashing when replying or forwarding a mail.
I built/installed an recent 7.99.21 kernel/userland on a dual processor Dell
AMD64 system and then built a whole raft of packages (pkgsrc current) and did
some basic testing. Pretty much everything worked as expected, including
sound on kde etc. I copied the binary packages and config files to two other
AMD64 systems, a T400 laptop also running 7.99.21 and a quad processor system
(same release) which is my main desktop system and I spotted the problem on
the latter. Kmail worked fine for new mails/reading mail, but if you replied
or forwarded a mail inline it crashed - a segment violation.
Strangely the laptop didn't suffer this problem whatsoever and I assumed some
slight variation of config files/libraries/etc was triggering an issue in
kmail on the other systems.
However if I removed the laptop disk and used it to boot the other systems,
the kmail problem showed up - and now there was no doubt the software was the
So it would appear that a userland program which should be insulated
from the underlying hardware by the kernel is being affected by different H/W.
The only thing kmail is doing is opening a new window under X and no other
program has shown the problem so I am discounting an issue with the underlying
X video kit. If a mail was forwarded as an attachment then it worked fine on
any system so I guess its something to do with memory allocation. The systems
all have differing amounts of physical memory - the laptop has 3g, the Dell 4g
and the other system 16g.
Can anyone suggest what's going on. A pkgsrc build from about a year ago on a
correspondingly old version of current has worked faultlessly with kmail
behaving as expected on all three systems... A more recent build of the latest
current + pkgsrc still shows the same problem on the Dell - but I haven't
tried moving the disk on the laptop yet.
