(^^^ hope this works, will fix it if not.) Hello, thanks for maintaining parted. On Hurd, libparted devices can be created directly from "store" objects through the hurd-specific ped_device_new_from_store() function. Such devices don't get registered into linked list and have a non-initialized 'next' field. A later call to ped_device_destroy() will make _device_unregister() mangle the mailing list as a result. A crash will result the next time the list is used, for instance on exit when destroying all devices. For what it's worth, ped_device_new_from_store() is used for the (preliminary) user-space partitions support in Hurd's libstore, which will probably be needed for debian-installer. The attached patch makes _device_unregister() do nothing if the device was not found in the list. -- Jeremie Koenig <j...@jk.fr.eu.org> http://jk.fr.eu.org
