Comment (by korli):
Having looked deeper, it seems the crash happens in sbr_make_f_master()
for some unknown reason. For instance, the value of the sbr pointer
parameter changed to null (nothing in the code indicates such a change).
This is as if the stack was being corrupted after the line
{{{
num_bands_0 = lrintf(half_bands * log2f(sbr->k[1] / (float)sbr->k[0])) *
2;
}}}
It looks like calls to libroot functions. Maybe these don't behave
correctly because of current ffmpeg build options on GCC2 (-fomit-frame-
pointer -fPIC).
It would be interesting to check the behavior on GCC4.
