I noticed that /usr/bin/xz crashed with signal 10 on a Feroceon 88FR131 rev 1 CPU and traced back to an unaligned 16 bit memory access in liblzma. This is enabled by TUKLIB_FAST_UNALIGNED_ACCESS in src/lib/liblzma/config.h. Uncommenting this line fixed the problem. This may cost some performance on non strict aligment architectures (e.g. x86, most ppc). Passing it via CFLAGS instead of config.h based on architecture would fix this problem.home | help
