These patch-shebang failures are unrelated to the build, as these are
scripts to download more quotes from the web, which are never invoked.

As embarrassing as this is to say, this appears to be an out-of-bounds
read in daikichi (if you check out the source and invoke the actual
command, it will print "Assertion '__pos <= size()' failed." with a
long type qualifier), which is raised somewhere from 
   std::ostream &operator<< (std::ostream &o, const header& header)
in daikichi-io.cc.

As nothing whatsoever is written, this may be already on the first
line, but with the ostream likely being buffered could be any of those
writes.  I'll dig deeper once I have some more time.

Cheers
