memory corruption when user-interrupts and tcp

Reported by: kristianlm Owned by:

Estimated difficulty:


It seems user interrupts from csi, when reading from tcp ports causes memory corruption. As shown in this paste:

~$ csi -n

I am reproducing this on Linux 3.18.6.

I can no longer reproduce this bug. It looks like this was fixed at the ICC with 4e32262036806b2fc51964e518135fcd3de3a79b
