Hi, Since v1.4.7 DTC FTBFS on Debian sparc64 because of a bus error when running the type-preservation.dts test. Build logs are available here: https://buildd.debian.org/status/logs.php?pkg=device-tree-compiler&arch=sparc64 It may be an alignment issue introduced in this commit: https://github.com/dgibson/dtc/commit/32b9c61307629ac76c6ac0bead6f926d579b3d2c I have no idea how to fix this, but the following gdb backtrace (from v1.6.0) may help someone else: Reading symbols from dtc...

I'm not subscribed to this list. Best regards, Tom Turelinckx
