The frame that causes the Valgrind errors

Yes, I can.

The problem only shows up with Valgrind so the only way to find the offending
packet was to split the capture into pieces until I got down to 1 frame. I
attached that one frame.

What's really amusing is that that frame loads clean in Wireshark (no sign of
an exception) yet Valgrind still complains.

I tried building with ASAN and it doesn't complain either.

It's quite possible it's a Valgrind bug.
