Assertion failed when DTS out of order in asfenc.c

[wim_arbor]

Summary of the bug:
A transcoding of a ts with a signal loss to asf results in a Assertion asf->packet_timestamp_end >= asf->packet_timestamp_start failed at libavformat/asfenc.c:704 and causing an APPCRASH popup in windows. The last two PTS of the video stream are 4322553629 and 4322551520, which is out of order. Adding -fflags +genpts+igndts still produces the same result.

How to reproduce:
