Ah, but your second URL creates this error when built with ASAN:

The difference seems to be that the first URL that you mention is downloaded 
via HTTP/2. The second URL is downloaded vias HTTP/1.1.

Hopefully will find time to fix this in the next 1-2 weeks (anyone else can do 
that as well - seems to be very simple to fix).
