corrupted size vs. prev_size #5

Closed marioortizmanero closed 4 years ago

When running the example script, the following error may be displayed:

corrupted size vs. prev_size
zsh: abort (core dumped)  python3 example.py "Queens of the stone age no one knows"

This can happen in the middle of the execution, or right after the program ends. It might be related to the memory usage (if sizeof(double) == 8):

Input array 1: 8 * 720,000 = 5,760,000B
Input array 2: 8 * 720,000 = 5,760,000B
Input array 1 zero-padded: 8 * 1,440,000 = 11,520,000B
Input array 2 zero-padded: 8 * 1,440,000 = 11,520,000B
FFT result array 1: 8 * 720,000 = 5,760,000B
FFT result array 2: 8 * 720,000 = 5,760,000B
IFFT result array: 8 * 1,440,000 = 11,520,000B

= At least 57600000B = ~55MB of RAM used. Maybe it's overcommitting RAM? pmap returns ~304MB as the total usage.

It could also be caused by the AddressSanitizer warning for fftw_alloc_real (https://github.com/marioortizmanero/vidify-audiosync/commit/478cbb0ac9cf8d7bdb50b71f6b1e5c2153d2e5cd).
