SUMMARY
ldexpf() does not set OF flag when running in valgrind

STEPS TO REPRODUCE
1. Create fenv.c containing:
#include <stdio.h>
#include <fenv.h>
#include <math.h> // ldexpf()
int main() {
  float inf = ldexpf(0x4000, 0x78); // Overflow
  printf("fetestexcept(FE_OVERFLOW) = 0x%x\n", fetestexcept(FE_OVERFLOW));
}

2.  Build with:
Build with: gcc -g -lm fenv.c -o fenv

3. 

OBSERVED RESULT
$ ./fenv 
fetestexcept(0x8) = 0x8
$ valgrind ./fenv
