 Hi experts,

 I compiled the following code with pgcpp / PGI 10.4 on linux.

 /opt/pgi-10.4/linux86/10.4/bin/pgcpp main.cpp -o erf.exe
 -------------------
 #include <math.h>
 #include <boost/math/special_functions/erf.hpp>
 int main()
 {
    double val(1.0);
    printf("BOOST : %-20.15E\n", boost::math::erf(val));
    printf("MATH_H: %-20.15E\n", erf(val));
 }
 -------------------

 Output is as follows:
 BOOST : 8.368481544380342E-01
 MATH_H: 8.427007929497149E-01

 The value computed by BOOST is incorrect. The same code will give the
 correct value when compiled with VS2012 with Windows 7-64 bits OS.

 My linux box is running SUSE Linux Enterprise Desktop 10 SP2 (x86_64)

 Can you please help troubleshoot the problem? Other basic statistic
 functions will also return wrong values such as cdf and quantile of
 standard distribution.

 Thanks a lot,

 Jacques Desfosses
