You shouldn't call upsdrv_cleanup() in the reconnect_ups() function. Besides free'ing the reopen_matcher variable (which is definitly not what you want, since it will be used for opening the device a few lines down), it will also call usb_close() that will trigger a double free corruption in Linux on reconnect. Calling usb_close() is needed for SUNOS only, but this is already handled by libusb_open() in libusb.c.
