Comment # 4
on bug 11790
from Peter Wu
Can confirm that this is a real issue. Affects at least Wireshark master and
2.0.0. 1.12.8 somehow did not crash on the capture.
Workaround: disable 802.11 decryption:
tshark -r 1.pcap -o wlan.enable_decryption:0
--
ASAN backtrace for v2.0.0-69-g6793a03 is slightly different, possibly because
master has v2.1.0rc0-460-gcb3dd95:

As far as I can see, the bug reaches far back. Maybe there is a way to trigger
the issue in other versions, but I did not check.
