We ran into an interesting error with lcrash when saving a crash dump. While copying the crash dump lcrash ran into an error and displayed the message "Error: dump flags in dumpdev page index invalid". On each subsequent reboot lcrash would again attempt to copy the crash dump, and would also encounter the same error. Each attempt would write some number of blocks and increment the bounds file contents, resulting in a continual series of less-than-useful crash dump files.
In this particular error __kl_dump_retrieve returns a status of 0 (line 247 of kl_savedump.c), which prevents the caller (kl_dump_retrieve) from erasing the dump. Every other failure case returns a status of 1, which seems more appropriate. It's probably advisable to modify this line to return a status of 1 to be consistent and to allow the crash dump to be erased.
