Can only reproduce with gcc:14, albeit no idea what's going on here. (it does bundle embree at src/3rdparty/embree)
I've tried some combinations of C{,XX}FLAGS flags and this seems to be caused by -march=native (or in my case, -march=znver2)? make.conf fragment: # COMMON_FLAGS="-O3 -march=znver2 -pipe -ggdb3" # original, bad # COMMON_FLAGS="" # 1. good # COMMON_FLAGS="-O3" # 2. good # COMMON_FLAGS="-O3 -march=znver2" # 3. bad # COMMON_FLAGS="-O3 -pipe" # 4. good COMMON_FLAGS="-O3 -pipe -ggdb3" # 5. good CFLAGS="${COMMON_FLAGS}" CXXFLAGS="${COMMON_FLAGS} -D_GLIBCXX_ASSERTIONS" gcc version: gcc version 14.0.1 20240124 (experimental) 3de031c96f28f19a68ea2080260d8fd2c78828ee (Gentoo 14.0.1 p, commit ddeac849ac4c3fecdf591ab6fb075cc6c5afdbff)

Just a guess given haven't really looked at this yet, but if it's related to -mavx then I'd suspect [1] and [2] being related. [1] is probably missing something with gcc:14 or something like that. [1] https://github.com/qt/qtquick3d/commit/7980cfd0 [2] https://github.com/qt/qtquick3d/blob/6b990522/src/3rdparty/embree/CMakeLists.txt#L64
Suppose that a lame workaround without disabling avx for the entire package or trying to figure out what needs disabling could be to just: qt_internal_extend_target(BundledEmbree COMPILE_OPTIONS -mno-avx)
ftr this will be worked around alongside the 6.6.2 bump soon'ish, not planning to fix this in 6.6.1
