[FFmpeg-devel] vorbis_dec.c on sh4 architecture : floating point exception

[Vincent Penné]

We are trying the vorbis decoder on SH4 architecture. It raises randomly 
some  floating point exceptions.

It appears that some floating point arrays aren't initialized to any 
specific value at allocation time in "vorbis_parse_id_hdr" function, 
introducing random and possibly invalid floating point values. 
(apparently , sh4 is a bit touchy with invalid floating values)

Turning the av_malloc calls into av_mallocz calls fixes the problem. As 
it is initialisation code, there should be no impact on performance.
