is this a bug? erratic segfaults

[Ramon Diaz-Uriarte]

I've started getting bzr segfaults. Just asking for the help leads to
a segfault:


ramon at ameiva:~$ bzr help
Segmentation fault

And this happens with at least two regular users and root.


If I change users and directories, eventually the problem apparently
goes away. If I look into the kernel messages I see things such as:

bzr[24856]: segfault at 0000000000001008 rip 00000000004390e9 rsp

Nothing else seems to be wrong with the machine.

This is running Debian (2.6.8-12-amd64-k8-smp) with bzr-0.13.

This started happening after a (not-real?) CRC check failure during a
push. I just run things again without trouble (the push, and several
checks).

I understand this might be useless, since I cannot reproduce it at
will. Is there any extra info I can provide?


Best,

R.
