Yes, I've experienced this too. : It won't dump core if file is smaller (say a few KB) or the option M : is not used.
I've put together a set of 3 QIC-150 tapes with debian 1.2. Reading/testing every single tape back is ok, where of course the overlapping files are lost. Reading it back with "M"-option makes the first tape give a Segmentation fault at an offset of about 60MB. At the first glance I thought it were a bad media, but the critical point has shown to be exactly at the same byte on another media. Anyway, I had to put in the variable LD_PRELOAD=/usr/lib/libgnumalloc.so.5 in debian 1.2 to make tar go without seg fault, but this didn't help against that multi volume trap. Then I realized the same behavior on this special set of tapes at another system, running an older kernel and another distribution, but the same tar version "GNU tar 1.11.8". So, is this fault really ((tar-version) + data)-dependent? I usually read my tapes back with the -t option, to avoid media problems and know in advance, what surely will bit me in the future, and worked around with reading the tapes as single tapes. -Andreas. -- Uni Wuppertal, FB Elektrotechnik, Tel/Fax: (0202) 439 - 3009 Dr. Andreas Wehler; [EMAIL PROTECTED] -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
