DWhite seems to think that it may be pointer > corruption in libc, specifically snprintf, fopen, strlcpy or strncpy Have you checked your /var/db/pkg/<port_name>/+CONTENTS files? For some reason some ports on my relatively stale -CURRENT box had these files truncated to zero length, and this caused some package tools (namely pkg_version) to crash. The procedure to read plist simply returns with all plist struct members set to zero without indicating any errors when CONTENTS file is empty, and the pkg_version crashes trying to defererence null 'origin' pointer. > Here is the backtrace > > Program received signal SIGSEGV, Segmentation fault. > 0x28204e57 in strlcpy () from /usr/lib/libc.so.5 > (gdb) bt > #0 0x28204e57 in strlcpy () from /usr/lib/libc.so.5 > #1 0x0804a003 in pkg_do (pkg=0x0) > at /usr/src/usr.sbin/pkg_install/version/perform.c:169 > #2 0x08049bfc in pkg_perform (indexarg=0x0) > at /usr/src/usr.sbin/pkg_install/version/perform.c:71 > #3 0x08049a45 in main (argc=1, argv=0xbfbffc0c) > at /usr/src/usr.sbin/pkg_install/version/main.c:79 > #4 0x08049879 in _start () -- Alexander Kabaev To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
