mkisofs segfaults on me sometimes. It happens only under certain circumstances, for example when piping mkisofs data into a buffer, piping buffer data to cd writer, and then only when mkisofsing a certain set of files. This is not random - the problem will always occur in this combination, but vanish as soon as I change the set of files or pipe into a file rather than burning on the fly. What makes it hard to reproduce is that you first have to find a set of files that makes the segfault happen. I'll attach (part of) a backtrace of a coredump I got; I don't know if this is useful to anyone at all. I fear that optimized Gentoo systems are not exactly suited for useful debug information. If anyone wants to have a look at the problem though, I'll be happy to provide more detailed information about it.

and with cdrtools-2.01.01_alpha01 ?
mkisofs seems to be identical for cdrtools-2.01.01_alpha01 - it reports the same version number "mkisofs 2.01 (i686-pc-linux-gnu)" and segfaults in the same situation.
UTF-8 filesystem with Umlaute-files?
No answer within a month. Closing.
