`Illegal instruction (core dumped)` on Alpine 3.8
See original GitHub issueRelated to https://github.com/lovell/sharp-libvips/issues/13 (by mistake, closing the other issue).
Was able to repro:
node -e "require('farmhash').hash32('sdflkjsdf')"
The most puzzling thing is why all the sudden this is happening.
Verified performing an npm rebuild farmhash resolved. Probably more of an issue from my end as to why different instruction sets are supported between the docker build environment and the release environment. But i’d at least like to better understand the exact difference and perhaps the pre-built could work around the issue?

Prebuilt binaries are not currently provided for musl-based Linux such as Alpine.
If the build host and runtime target differ you can specify the target architecture at compile time:
I suspect you have just started using build servers with support for AVX2 intrinsics.
Appears to be an ordering of instructions problem since the default config already supplies
-march=native. Going the route of only adding opt-out instructions (ala-mno-avx2 -mno-bmi2) seems to do the trick so far.I’ll close this topic for now, but perhaps others will find it of use. Thanks again.
