Re: [LAD] is this a compiler issue??

i have written a channel class, which collects data from (file) sources and copies it to a buffer. Jack will get this buffer and put it into his streams. So far, I think, this is a normal design with the following code for (unsigned int n = 0; n < nframes; ++n) { pBuffer[n] += pFrames[n]; pBuffer[n] *= volume; } i know, it's not really optimized. But it works as an example. as you can think, pBuffer and pFrames are float* and volume is also a float. now it happens, when the volume is 0, after 3-5 seconds, the CPU will run into 100%. a workaround is the following before the loop if(volume < 0.0000001) volume = 0.0000001; But i try to understand, what happens here. Is the compiler overoptimizing zeros.
