This index file is some kind of cache that is machine dependent. Someone has opened that crash dump on a 64 bit machine and you fail to open it on a 32 bit machine now. Removing that index file should resolve this. It's not possible to detect that case since the index header only has - dump version - magic number - time stamp Adding a new header would make the header format incompatible -- therefore, I decided to implement a architecture independent format. The new lcrash is still able to read all index files, but creates a new format that can be read on a machine on another architecture then. I attached the patch. I'd like to get opinions from upstream before I'll add it to our package (I hope there are no vetos against this). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
