VBoxSDL segfaults during startup, slow ssh connections

[Christopher]

Dear VirtualBox team. It seems, that somehow I'm attractive for segfaults. Anyway, here are the problem descriptions:

Host: openSUSE-10.3 + all Patches, Athlon64 in 32-bit mode, kernel-default-2.6.22.9, glibc-2.6.1

Guest: WindowsXP SP2 + all patches, German, guest-additions-1.5.6 installed

Binary: VirtualBox-1.5.6_28266_openSUSE103-1.i586.rpm

SGID-vboxusers: VBoxSDL is started with SGID-vboxusers wrapper

Problem-1: If I call VBoxSDL over an ssh-forwarded (-X and -Y tested) and rather slow TDSL-cable connection (2 MBit), it segfaults always:

my-laptop@home -> ssh -> computer@uni -> VBoxSDL ==> segfault

I admit, that this is much to slow to work with. But I was just curious. If I call VBoxSDL from the same computer over a fast ssh-connection, I do not get any segfaults:

my-laptop@uni -> ssh -> computer@uni -> VBoxSDL ==> NO-segfault

Core dumps and segfaults of three VBoxSDL calls:

Problem-2: I had once and only once a direct VBoxSDL core dump, e.g. started without ssh from a terminal window. Here is the core-dump (unfortunately without log):

Maybe the problems are connected.

Many thanks for your help and your good work.

Best regards

Please could you check if the recent version 1.6.2 works? If not, please could you provide another core dump for 1.6.2?

Please reopen if the problem still persists. There was a bugfix in version 1.6.4 which could solve this problem.
