VS 2017 32-bit doesn't run this test:

CC      tests/checkasm/vf_hflip.o

I don't know why. 64-bit VS 2017 tests vf_hflip, 32/64-bit mingw also.

If I run this test from command line it works (in 32-bit VS 2017):
$ tests/checkasm/checkasm --test=vf_hflip --bench --seed 1616253308
benchmarking with native FFmpeg timers
nop: 19.3
checkasm: using random seed 1616253308
 - vf_hflip.hflip_byte  [OK]
 - vf_hflip.hflip_short [OK]
checkasm: all 2 tests passed
hflip_byte_c: 274.1
hflip_byte_ssse3: 18.1
hflip_short_c: 194.1
hflip_short_ssse3: 18.9

Any ideas?
