I was not able to reproduce this issue with a Wireshark build from git
using `cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DENABLE_ASAN=1
~/wireshark && ninja wireshark`:
* master v3.1.0rc0-1166-g1e7f85e02f66
* master-3.0 v3.0.3rc0-46-gd094b56a9b4e
I can reproduce the crash with the same build settings and:
* master-2.6 v3.1.0rc0-1168-gc0822c187b
No idea what has changed since 3.0, but I guess you can safely upgrade
to Wireshark 3.0 now to fix this issue.
