[LMMS-devel] Some new flying bugs...

[Stephane T. <st...@ne...>]

Hi,

First of all, thanks to Tobias for the last release of LMMS, the preview
bug I noticed is now fixed.

I found a new bug in lmms-cvs20060222 :

In a new song, open the piano-roll editor of the default
triple-oscillator, put a note, then hit play in the piano-roll editor.
While playing if you remove the triple-oscillator then lmms crashes.

Program received signal SIGSEGV, Segmentation fault.

I use ALSA rather than jack for audio to reduce "third-party bugs". I
don't give lmms acces to realtime because I also noticed some CPU
overload (but I can't say exactly why it happen)... If lmms has realtime
capabilities it freezes my box in this case.
Is it a problem to run lmms without realtime capabilities ?
