* this problem is known: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354305 * this is linked to the reconnexion mechanism, and has appeared since the add of mfrs other than MGE since it wasn't present before (maybe sits inside the libusb/usb_close() function). * It's also easy to reproduce (tested on 2.0.3 and trunk): 1) launch newhidups, and wait for some notification 2) unplug the usb cord and wait a bit... you got it! * a gdb trace (won't tell much without compiling libusb in debug mode!): ... =>Got to reconnect! ================================================== = device has been disconnected, try to reconnect = ================================================== Closing device *** glibc detected *** double free or corruption (fasttop): 0x0806a5e0 *** Program received signal SIGABRT, Aborted. 0xb7e3ba97 in raise () from /lib/tls/libc.so.6 (gdb) bt #0 0xb7e3ba97 in raise () from /lib/tls/libc.so.6 #1 0xb7e3d329 in abort () from /lib/tls/libc.so.6 #2 0xb7e6f896 in __fsetlocking () from /lib/tls/libc.so.6 #3 0xb7e75fcf in malloc_usable_size () from /lib/tls/libc.so.6 #4 0xb7e7636a in free () from /lib/tls/libc.so.6 #5 0xb7f437a7 in usb_close () from /lib/libusb-0.1.so.4 #6 0x08050e85 in libusb_close () #7 0x0804ffd2 in HIDCloseDevice () #8 0x0804ab06 in reconnect_ups () #9 0x0804a022 in upsdrv_updateinfo () #10 0x0804bc4f in main () I'll investigate it and get back asap.
