Bug #1740

Updated by tuxillo almost 10 years ago

Some Linux binaries compiled with -ffast-math crash with floating 
 
 point exception. There also is a warning in dmesg: 

 

 FXRSTR: illegal FP MXCSR 00009fc0 didinit = 0 

 

 This is a bit unfortunate as for some reason the procps package 
 
 (pkill, pgrep, uptime, etc) is compiled with the -ffast-math switch 
 
 and the utilities crash. 

 

 The following mini-program shows the crash when compiled with 
 
 -ffast-math (as Linux binary): 

 

 #include <stdio.h> 

 

 int main(int argc, char **argv) { 
         
         double d; 

         

         scanf("%lf", &d); 
         
         printf("%f\n", d); 
 
 }
