If I try reading the file from
http://www.aktiv-verlag.com/~webvideos/testvideos/2010/panasonic/Panasonic_HDC_TM_700_P_50i.MTS
(which is also part of the Wireshark menagerie, so it might be attached to some
other bug) in TShark or reading it in Wireshark, it appears to get stuck,
spending lots of time in
static void
LINK_FRAG(fragment_head *fd_head,fragment_item *fd)
{
fragment_item *fd_i;
/* add fragment to list, keep list sorted */
for(fd_i= fd_head; fd_i->next;fd_i=fd_i->next) {
if (fd->offset < fd_i->next->offset )
break;
}
fd->next=fd_i->next;
fd_i->next=fd;
}
Some debugging printouts seem to indicate that there's a list of fragments with
at least two sequential fragments having a fragment offset of 0.
