Package: ecasound Version: 2.4.4-6 Severity: normal *** Please type your report below this line ***
Segfault on exit/interrupt by TERM signal (kill or "Ctrl-C"); hang on small buffer value in args. Firstly about hangs, it's short. When I tried launch ecasound with small buffer option, it hung, and so was killed with -9. The command line follows: ecasound -b:128 -i ~/music/somefile.mp3 -o /dev/dsp I don't know should it be named problem or bug at all, but nevertheless it exists. Quite unsure if I had to create separate report mail, so it is included here. Secondly, about segfaults on interrupt. (Note: may be it's a problem of plugins?) I have met this problem trying examples from http://www.eca.cx/ecasound/Documentation/examples.html, these command lines: ecasound -i null -o /dev/dsp -el:sine_fcac,440,1 ecasound -i:null -o:/dev/dsp -pn:metronome,120 Segfault happens not always, but usually. Terminal output for "kamerton" run and two (normal and segfaulted) for "metronome" runs follow. Same results for "Ctrl-C" stops and kill -15. The most of other example command lines from that address didn't cause segfaults on terminate. $ ecasound -i null -o /dev/dsp -el:sine_fcac,440,1 ******************************************************************************** * ecasound v2.4.4 (C) 1997-2005 Kai Vehmanen and others ******************************************************************************** - [ Session created ] ---------------------------------------------------------- - [ Chainsetup created (cmdline) ] --------------------------------------------- - [ Connecting chainsetup ] ---------------------------------------------------- (eca-chainsetup) 'rt' buffering mode selected.
