HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to log2_frac().Shouldn't the line c...

hi Jean-Marc, the memory after the allocated space is definitely destroyed. It took me some time to find out why. I expected local arrays to be allocated on stack, not on the heap. The function get_required_bits allocates a local array uint32[] which will be located on heap right after the array fromcompute_pulse_cache(), what made me think it was written behind its end. I am sorry for the panic ! ? best regards, Marko. -------------- next part -------------- An HTML attachment was scrubbed... URL: htt...
