opus - Mar 2010 - Threading issues with CELT?

Hi,

I'm using CELT encoder/decoder from several threads (but *different*
encoder/decoder objects from the different threads) and I have various crash or
"abort" (like ec_byte_write_at_end calling "celt_fatal("byte
buffer collision");"

It there any threading issues to known when using CELT?

Thanks

Stephane Letz

Hi Stephane,

not sure if that helps: 

I justed wanted to mention that I am also running CELT in the same way but do
not experience such issues (Linux and OS X).

Best

You cannot safely use the global stack with multiple threads, so one  
of VAR_ARRAYS or USE_ALLOCA must be defined. The former requires a  
C99-compliant compiler. The latter requires the POSIX function alloca.  
If neither is defined, the global stack is used as a fallback, and is  
likely what is causing your problems.
