I use either
wget -t0 -c -S <url>
or
wget -t0 -c -S --trust-server-names <url>
Seems to happen more often with larger files. I don't remember any
special output when the crash happens - just the standard progress
bar, and Windows' crash notification.

I thought about the progress bar, since it does behave a bit weird on
Windows - specifically, if the filename is scrolling, once it starts
off-screen, the last letter keeps getting repeated, while the rest of
the progress bar stops updating, however the crashes seem to happen
regardless of how the filename is displayed.

The annoying thing is that I haven't even had a crash since I set up
DrMingw as just-in-time debugger (debugger that Windows invokes only
when a crash occurs, and which otherwise isn't running). The last time
my build crashed for me was about a month ago, downloading some ISO
file at work, while I hadn't had it crash on my home computer in well
over a year (I even tried setting up a batch file that just ran wget
in a loop and leaving it in the background, but it wouldn't crash).
