Original commit message from CVS: * gst-libs/gst/resample/resample.c: (gst_resample_sinc_ft_s16), (gst_resample_sinc_ft_float): Remove use of static temporary buffer. This code was obviously not supposed to last long, but it's stuck in our ABI, so it required a little hack to make it ABI-compatible. Fixes #142585. * gst-libs/gst/resample/resample.h: same.
