Summary: SPEEX_SET_COMPLEXITY causes speex_encode_int to have a Data access CPLB miss

Details:

Setting the Speex complexity as follows causes speex_encode_int() to have a Data access CPLB miss. This causes the application to blow up.

tmp = SPEEX_DEFAULT_COMPLEXITY;

speex_encoder_ctl(speex->enc[i].state, SPEEX_SET_COMPLEXITY,&tmp)

speex_encode_int works correctly when the complexity is not set.

The complete error messages are:

Data access CPLB miss

- Used by the MMU to signal a CPLB miss on a data access.

Jason:

Can you run the application (all built with -g) inside gdb, and get a

backtrace?

--- Jason Hennigar 2008-09-15 20:10:49

Hi Robyn,

The application is built with the -g option but I have not run it inside gdb.

Due to a tight deadline I won't be able to investigate this problem until the

weekend.

Cheers!

Jason
