[Debian-med-packaging] Bug#1107772: gmap inlining failed in call to ‘always_inline’ ‘_mm_alignr_epi8’: target specific option mismatch

[Jochen Sprickerhof]

Source: gmap
Version: 2024-11-20+ds-2
Severity: normal

Hi,

I noticed that the build of gmap fails on reproduce.debian.net using a
Intel Xeon X5690 but succeeds on my system with a i7-8565U:

https://reproduce.debian.net/amd64/#gmap

The relevant log is:

It is using SSE3, SSE4 and AVX2 which are all not guaranteed according
to:

https://wiki.debian.org/ArchitectureSpecificsMemo#amd64

This looks like a baseline violation to me.

Cheers Jochen
