Hi,
$ gcc --version
gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0
Given this code snippet:
float a = 0.0F;
float b = -0.0F;
printf("a: %f, signbit(a): %d\n", a, signbit(a));
printf("b: %f, signbit(b): %d\n", b, signbit(b));
Result:
a: 0.000000, signbit(a): 0
b: -0.000000, signbit(b): 0
I would expect:
a: 0.000000, signbit(a): 0
b: -0.000000, signbit(b): <something not 0>
... according to: http://man7.org/linux/man-pages/man3/signbit.3.html
Are there some flags in the your build script which cause this problem?
If I compile the code without FFmpeg build script, but with standard
configuration, I get the expected result.
