Hi,

while resizing images through sharp using libvips, upgrading
libjpeg to 2.1.5 made it crash with:

Thread 15 "libvips worker" received signal SIGILL, Illegal instruction.

0x00007ffff00a109f in jsimd_idct_islow_avx2 () from /lib/x86_64-linux-gnu/libjpeg.so.62

I have forwarded the issue upstream, the fix is probable a search and replace (s/SIGILL/SIGKILL/g), but I'll give upstream some hours to react.
