Comment (by accessays):
I've managed to narrow it down to two urls:
1. https://ir-na.amazon-adsystem.com/e/ir?t=thedigitalt02-20&l=ur2&o=1
2. https://ir-na.amazon-
adsystem.com/e/ir?l=w41&t=thedigitalt02-202&o=1&cb=1501216857775
Both are Amazon's ad system urls, probably used for tracking. Problem
comes from the fact that the web server uses LF (\n) instead of CRLF(\r\n)
to separate lines in headers, and that causes Web+ to crash (uint overflow
and thus segment violation).
Looking at the RFC https://tools.ietf.org/html/rfc7230#section-3.5
{{{
...
Although the line terminator for the start-line and header fields is
the sequence CRLF, a recipient MAY recognize a single LF as a line
terminator and ignore any preceding CR.
...
}}}
Which hints that such behavior may be considered normal. Firefox and
Python Requests (Linux) load the page without errors, tho headers get
messed up - instead of ''Connection'' header is called ''nnCoection''.
