zdump -v does not correctly work on alpha. cat /proc/cpuinfo cpu : Alpha cpu model : EV45 cpu variation : 7 cpu revision : 0 cpu serial number : system type : Avanti system variation : 0 system revision : 0 system serial number : AY cycle frequency [Hz] : 267895671 est. timer frequency [Hz] : 1024.00 page size [bytes] : 8192 phys. address bits : 34 max. addr. space # : 63 BogoMIPS : 529.40 kernel unaligned acc : 0 (pc=0,va=0) user unaligned acc : 0 (pc=0,va=0) platform string : AlphaServer 300 4/266 Tested with zdump 7.64 and the last available version 8.3 on tzcode2007b.tar.gz My report is #412569 against libc-2.3.2.ds1-22sarge5 and gcc-3.3.5-13 on debian BTS After compilation of zdump from tzcode2007b.tar.gz with make zdump alpha300:~# ./zdump --version @(#)zdump.c 8.3 alpha300:~# ./zdump -v /etc/localtime /etc/localtime -9223372036854775808 = NULL /etc/localtime -9223372036854689408 = NULL As it fail too with this last zdump available, I would think I need to report it there too. I find other report related to 64bits arch on debian BTS #266438: zdump -v causes core dump on IA64 Linux Package: libc6.1 (2.2.5-11.2; fixed: glibc 2.3.5-3); #402776: zdump -v errors on 64 bit architectures Package: libc6.1 (glibc 2.3.6.ds1-8, 2.3.6.ds1-10); Gilles
