Thanks for the tips Richard, but after some additional testing and some head-scratching, I discovered the source of the 
problem was something in my profile, because if I switched to a pristine profile, then master ran fine.  Through 
divide-and-conquer/trial-and-error, I discovered that it was due to enabling the transum dissector, although I can't 
figure out why enabling the transum dissector causes this, and then only for master.  Enabling it for 2.6.2 seems fine.

Maybe someone could just confirm if they also experience this exception if they enable the transum dissector?  If 
confirmed, I will file a bug report.

Confirmed on the latest master. Enabling transum crashes wireshark.

The exception, for reference:

Unhandled exception ("proto.c:6497: failed assertion "(guint)hfid < gpa_hfinfo.len" (Unregistered hf!)", group=1, 
code=6)

Thanks.
