Bug ID: 58327
Summary: Problem of quadmath in connection with SDL2
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libquadmath
Assignee: unassigned at gcc dot gnu.org
Reporter: u.weber at gipko dot de
"quadmath_snprintf" gives strange results, when SDL2
(http://www.libsdl.org/download-2.0.php) is additionally included. I'm using
"MinGW" with "DevC++" or "Code::Blocks". The short program:
extern "C" {
#include "quadmath.h"
}
#include "SDL2\SDL.h"
#include
int main(int argc, char* argv[])
{ char buf[128];
quadmath_snprintf (buf, sizeof buf, "%+-#*.20Qe", 46, M_PIq);
std::cout << "PI = " << (float)M_PIq << " / " << buf << std::endl;
}
gives the result:
PI = 3.14159 / +3.78539161562520278725e-4917
but when I delete or comment the line // #include "SDL2\SDL.h"
I get the expected result:
PI = 3.14159 / +3.14159265358979323846e+00
I guess this is related to Bug 51007 but I don't know how to fix this problem.
I would like to use "quadmath" and "SDL2" together.
