Hi, I've just upgraded to Kubuntu 15.10 and applied patches for libsoxr resampler to PA 6.0 that comes with the distro. I'm seeing crashes in the LFE filter if I use soxr-vhq resampler (I haven't tried the other soxr* variants yet). Is this a known problem? Below is the backtrace of one of the crashes. Program received signal SIGABRT, Aborted.

I realise 6.0+soxr is not an official configuration, but the patches are a rather straightforward backport of the code that is in master, so I suspect the same problem will be present in 7.x. If needed, I can provide the actual patch I'm using.
