That one might be "fixed" by not generating incorrect un-optimized code; the current code generates (008) ldb [0] rather than (008) ldb [1] when looking at the "type" subfield of the Frame Control field - that subfield is in the first octet. There might still be an underlying optimizer bug (there certainly have been ones in the past that have been fixed). ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
