Can you also please provide the backtrace from lldb for this core dump?

Surprisingly, the last call is:
> stat("/usr/local/share/icu/65.1/icudt65l/iso-8859_16-2001.cnv",0x7fffffffc998)

which comes from ICU. The entire website has been read from the socket, 
as you can see from the read in 2246.
Maybe it to convert the "charset=iso-8859-2" to LC_ALL value.

I would recommend to have a simple server built in PHP or Python and try 
the simplest site possible w/o CSS and then add one w/o fonts first.
