Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
%%%Using Ubuntu 64bit r46647.
Noticed a few weeks ago and figured it was a little minor to mention, but it does seem to be holding a debian bug report open:
I will point the debian bug to this report. Also, attached a sample crash output just in case (no gdb bt though, was release build, sry)%%%
Changed status to: 'Open'
%%%I setup a debug build and poked around a bit in code. Judging by the backtrace and the code, my theory is that set_engine simply calls "exit(0)" which then triggers the exit handlers, which in turn expect to decrement the references for some AUD pointers which haven't been setup yet in this type of minimal startup.
%%%
%%%Calling sound_exit() before exit(0) in set_engine() form creator.c avoids the issue. But think it's a bit more general issue with referencing audaspace?
Joerg, can you please look into this?%%%
%%%The bug is caused by the global reference counting map being deleted before all other objects gets deleted on exit. Fixed it via at_exit in revision 46662.%%%
Changed status from 'Open' to: 'Resolved'
