The .ps for process 7447 shows gnash::convert_raw_data (0x4330926) 
allocating the most part of memory (and growing).

The .txt doesn't contain address 0x4330926 but 0x4330925 (one-byte-less)
with same name, in the section "Heap allocation functions accounted for 89.7% of
measured spacetime":

  2.5% : 0x4330925: gnash::convert_raw_data(short**, int*, void*, int, int, 
int, bool, int, bool) 

That's called from:

  0x402D39B: gnash::media::AudioDecoderSimple::decode

What I don't understand is why AUdioDecoderSimple::decode is used rather
then AudioDecoderFfmpeg::decode

Is the ffmpeg media handler failing to register it's own audio decoder ?
