Thanks for this patch! A couple thoughts:

(1) Please follow the instructions here, in particular about the contents and format of the commit description: https://github.com/google/packetdrill#how-to-submit-a-patch-for-packetdrill

(2) Can you please document in the commit description the distribution and version number where you encountered this problem, and also document where you have tested the fix? (e.g. encountered on Debian x.y, and tested on Debian x.y and Ubuntu a.b, Fedora c.d, etc).

Thanks!
