Exp tests fail on FreeBSD

[danfe]

Running fastops_test program fails on the first very test as follows:

Testing exp (1/4)...
  AVX2 INEXACT UNALIGNED FLOAT (1/18)...
88.4665	2.63327e+38	2.63325e+38	7.24021e-06
Test FAILED
assertion failed false at TestFunc, .../fastops-1.0.0/fastops/ut/fastops_ut.cpp:177

This is on FreeBSD 13.0, the CPU is i5-7200U, same result regardless of the compiler (I've tried clang 11.0.0 and gcc 10.2.0).
