However, any time I ran any of the programs on the fixit floppy, they segfaulted. Even if I mount up the 4.7 fixit on a 4.6 system, the same thing happens (I attempt to ktrace the execution below): # echo foo | ktrace -id /mnt/stand/grep foo zsh: done echo foo | zsh: segmentation fault (core dumped) ktrace -id /mnt/stand/grep foo # kdump | m 12546 ktrace RET ktrace 0 12546 ktrace CALL execve(0xbfbffba7,0xbfbffaa8,0xbfbffab4) 12546 ktrace NAMI "/mnt/stand/grep" 12546 grep RET execve 0 12546 grep PSIG SIGSEGV SIG_DFL 12546 grep NAMI "grep.core" Unfortunately, the ktrace gives no info. I'm stumped at this point. ---------------------------------------------------------------------- | Jim Hranicky, Senior SysAdmin UF/CISE Department | | E314D CSE Building Phone (352) 392-1499 | | jfh@cise.ufl.edu http://www.cise.ufl.edu/~jfh | ---------------------------------------------------------------------- "Given a choice between a complex, difficult-to-understand, disconcerting explanation and a simplistic, comforting one, many prefer simplistic comfort if it's remotely plausible, especially if it involves blaming someone else for their problems." -- Bob Lewis, _Infoworld_ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
