Comment (by Marcin Wojdyr <wojdyr@…>):

 I haven't realized it before, but it depends on compiler flags.
 I'm using now Fedora 20, valgrind 3.9.0, GCC 4.8 and boost 1.54 and 1.55
 (both give the same result).
 I can reproduce the problem only with `g++ -Og`.

 But I've seen it with previous GCC versions (4.6 or 4.7, I'm not sure) and
 valgrind 3.8.1.
 I don't remember what optimization flags I used, but there was no `-Og` in
 previous versions.

 The minimal program I now use for testing is:

 {{{
 #!cpp
 #include <stdio.h>
 #include <stdlib.h>
 #include <boost/math/special_functions.hpp>
 int main(int argc, char **argv) {
     double x = strtod(argv[1], NULL);
     printf("%g\n", boost::math::erfc_inv(x));
 }
 }}}

 So as a workaround I'll just use a different compilation flags.
