Hi Guys
very short.
prog.c
#include <stdio.h>
int main()
{
float a=1.283;
while(1)
printf( "%f", a );
}
run with
$ ./prog.exe >/dev/null
in windows monitor process the process increase it's memory it arrive to many Gb.
It's not a machine problem, other PC have same problem.
Same program in wsl and MSYS2 works well!
This probably has to do with output buffering, and may happen even without
the >/dev/null since there are no line ends in the output. It may work with
stdbuf -o0 (as in: stdbuf -o0 ./prog.exe >/dev/null) but may cause the program
to run more slowly (each character is sent to the device, when then immediately
discards it). It would seem you're hoping for the internal libraries to
recognize the case of writing to /dev/null ...
