Mmh it's the same here. Also i686 and zita-convolver-3.1.0; I've tried

with gcc/g++ 4.6.3-1 and gcc/g++- 4.7.0-8 (Debian) and can not [yet]

reproduce the problem.
Here it's Linux 3.2.0-2-rt-686-pae #1 SMP PREEMPT RT

but that should not make a difference.

Thanks, fixed that.
start/stop was an easy workaround to do away with the artefacts that can

happen when bypassing and later re-enabling convolution.
Well, it would segfault trying to build the file-path to the IR sample

"IR-file-.wav" when jack reports a samplerate > 999999999Hz

but I think that's not it :)
