I have problems with qsynth-0.3.6 on both Mandriva-2010.2 and Mageia-1.

In both cases it starts fine THE FIRST TIME if I do

qsynth -a jack -r 44100 &

(I use JACK and the default is ALSA, so if I don't do that it just waits indefinitely, since JACK takes over the ALSA device).

BUT, after I do any kind of configuration (e.g. specify the soundfont), qsynth crashes upon the restart with the following message (address might vary):

*** glibc detected *** qsynth: corrupted double-linked list: 0x088ad550 ***

Here is another one:

** glibc detected *** qsynth: double free or corruption (fasttop): 0x09a72808 ***

Sometimes it is a segfault.

Looks like a memory corruption to me, but so far I can't pinpoint it.

I used qsynth-0.3.4 on Mandriva-2010.0 without any problems for a lo-o-o-o-ng time, many thanks!
