Hi, Jens,
So it really *is* closely related. The problem is in the symbol-db plugin:
https://github.com/GNOME/anjuta/blob/1f196dd119b41ce70f50c028946017e1c98d4d72/plugins/symbol-db/symbol-db-engine-core.c#L1561
There is a g_warning there (in fact the one you were seeing all along), but it really is a critical
error how the code is currently written, because there is no working fallback when shm is not usable.
Ok, so `shm_open ("/dev/pts/anjuta [...]` fails on your system and that causes the segfault.
Does this mean that the plugin needs to be fixed?
It doesn't do a good job at error recovery, as it stands shm support is required for the plugin to work.
I have 2 Gentoo system:
1. Gentoo + KDE 4 with Anjuta and GTK installed. It uses OpenRC.
2. Gentoo + GNOME 3 with Anjuta. It uses OpenRC.
The interesting thing is that on the first system I don't see that crash,
only on the second one.
Have you compared /etc/fstab on both systems?
Do you have any idea why? I will try to compare the USE-flags for
Anjuta on both systems
in the meantime.
I don't think the problem is use flag related.
And shm is mounted correctly:
$ mount | grep shm
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
I would try to comment out the last line of your fstab (and remount /dev/shm or reboot).
I can try to do that, but I want to hear your opinion on the question above.
Thank you.
I would compare fstab files and try to remove the devtmpfs line as I already wrote.
devtmpfs can be used for /dev (not /dev/shm), it is probably a typo or something.
Like I wrote before udev and the init system normally take care of mounting system filesystems like /sys,
/proc, /dev and even /dev/shm.
Here is the "mount" from the second machine:
igor@IgorDellGentoo ~/dbhandler/Debug $ mount
/dev/sda4 on / type ext4 (rw,noatime,data=ordered)
proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
tmpfs on /run type tmpfs (rw,nodev,relatime,size=201316k,mode=755)
dev on /dev type devtmpfs
(rw,nosuid,relatime,size=10240k,nr_inodes=251280,mode=755)
mqueue on /dev/mqueue type mqueue (rw,nosuid,nodev,noexec,relatime)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime)

tracefs on /sys/kernel/debug/tracing type tracefs
(rw,nosuid,nodev,noexec,relatime)
and here is /etc/fstab from it:
igor@IgorDellGentoo ~/dbhandler/Debug $ cat /etc/fstab
# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#
# <fs> <mountpoint> <type> <opts>
<dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/sda2 /boot ext2 noauto,noatime 0 2
/dev/sda4 / ext4 noatime 0 1
/dev/sda3 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,user 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
Thank you.
P.S.: I guess that was just a remnants from the old times install...
I will get rid of that and reboot.
