Speex dev - Jan 2006 - Experimental psycho-acoustic model

Happy new year all!

I have had a few issues with this sort of stuff- you could adjust NB_ENC_STACK
or SB_ENC_STACK (which ever you may be fiddling with) and see if the problem
goes away- could be the allocation for the vorbis psy tables takes up more 
space than
the current stack size allows (not sure how allocated?  Could be your 
settings for
supporting alloca/etc. are set different than jm, due to support for 
variable size arrays.
Haven't had a chance to look at the new(er) stuff yet, but that would be my 
guess...

Hi Tom,

None of the new code depends on the stack allocator, but I just fixed an
off-by-one overflow on the heap. Maybe that was the error and your
debugger is just reporting a wrong offset. Could you try what's in the
current svn (you were using svn already, right)?

Things seem to work better now.. But, perhaps the _analysis_output should 
be #ifdef'd or something? At the moment it generates noticable I/O, so I 
changed it to be just a return in my local version.
