The log is misleading. The actual crash happens in a different, later rustc, which does link to libllvm statically via librustc_driver: | error: rustc interrupted by SIGSEGV, printing backtrace | | /srv/pokybuild/yocto-worker/genericx86-64/build/build/tmp/work/core2-64-poky-linux/rust/1.75.0/rustc-1.75.0-src/build/x86_64-unknown-linux-gnu/stage1/lib/librustc_driver-cf7d845e2aab959c.so(+0xa75206) [0x768caf675206] | /srv/pokybuild/yocto-worker/genericx86-64/build/build/tmp/sysroots-uninative/x86_64-linux/lib/libc.so.6(+0x3b8e0) [0x768caea4c8e0] | /srv/pokybuild/yocto-worker/genericx86-64/build/build/tmp/work/core2-64-poky-linux/rust/1.75.0/rustc-1.75.0-src/build/x86_64-unknown-linux-gnu/stage1/lib/librustc_driver-cf7d845e2aab959c.so(+0x637aaa0) [0x768cb4f7aaa0] | Alex
