| Summary | 0001120: Crash using loop play | ||||

I too experience a lot of crashes with loop play. But it only seems to happen when the click is enabled. Note that I now use version 0.99 and this bug is still present. I can reproduce this bug every time; I create a new session and (without creating any tracks), create a loop range, enable the click track, then click on the "Play loop range" button twice. As soon as the playhead reaches the end of the loop range, Ardour crashes (for me, the Ardour window disappears without outputting anything in its terminal window). My system is also amd64, but with kernel 2.6.12-RT-V0.7.51-29. I was about to report the following as a seperate bug, but it sounds as though it could be the same problem: Ardour crashes if I adjust the loop range while it is playing that loop range. Again, it will only crash when I enable the click. The Ardour window completely disappears, and on one occaision I received the following output in the terminal window: *** glibc detected *** malloc(): memory corruption: 0x00000000012bebb0 *** and after loading Ardour back up and trying the same thing again: *** glibc detected *** double free or corruption (!prev): 0x00000000012e2260 *** although most of the time when I do this, Ardour crashes without outputting anything to the terminal window. |

Is this still an issue? |
|
|
if we get no feedback on this issue within a few days, we will close it since it is believed fixed. |
|
|
The bug report is a year and a half old. I wouldn't have a clue how to reproduce it at this point. I think it should be allowed to die from neglect if there are no similar reports elsewhere. Close it. |

done and done. |
