When compiling kstars-3.6.9 on aarch64, TestFitsData::testComputeHFR(NGC4535-3-FOCUS) fails: FAIL! : TestFitsData::testComputeHFR(NGC4535-3-FOCUS) Compared values are not the same Actual (d->getDetectedStars()): 125 Expected (NSTARS) : 126 Loc: [/home/buildozer/aports/testing/kstars/src/kstars-2.6.9/Tests/fitsviewer/testfitsdata.cpp(91)] (Apparently the 3.6.9 source was uploaded as 2.6.9) Other tests pass. It also passes on our CI infra, which runs on an aarch64 virtual machine, so it may be hardware / CPU related. Our builder has an Ampere Altra CPU.
