Boost compiles fine, OS Arch Linux, x86_64.

However, i got a regression in my software using boost::spirit::qi

See attached the program (i guess it does not qualify minimal, but i do 
not have time to trace it further), output of g++/valgrind for boost 
1.58 and for 1.59. There seems to be a signed/unsigned comparison issue 
and valgrind detects a conditional jump that depends on unintialized 
memory. In my code this showed up as 4 values read from the parsed file 
have wrong values albeit the 200 or so other values before and after are 
fine.

Best,
Oswin
