Hi all,
After I upgraded my system to fbtv 3.63, I now have a segfault :
I launch fbtv without any option, it starts correctly, but when I try to
do anything after (like changing the channel or disabling the top
line), it segfaults with the messages :
midi: snd_seq_event_input: Invalid argument
Oops: Segmentation fault
By recompiling it and gdb-ing the core file, I get the following backtrace :
#0 0x0804fa42 in midi_translate (h=0x806c5f0) at midictrl.c:258
#1 0x0804bf0e in main (argc=1, argv=0xbffffbb4) at fbtv.c:830
#2 0x4011a6ef ub __libc_start_main () from /lib/libc.so.6
The problem seems to be in an #ifdef HAVE_ALSA block although I don't
use the alsa driver. It might be related to the following lines in the
xawtv Change file :
* wrote some core to control xawtv/motv/fbtv via alsa midi.
Nothing specific in the log files (I can provide them if there are needed).
OTOH xawtv 3.63 works perfectly :-) but launching X is so slow (7s)
TIA
Fred
PS : I also had the libasound1-dev dependency problem which is
unrelated. There is also a small problem : the Debian source package
3.63 lacks a Build-Depends dependency on libasound?-dev.
