rednoise (v2.0.1) buffer overflow issue

[bwmeyers]

We've run into an interesting problem running the newer version of rednoise (v2.0.1) where we encounter the following error at runtime.

# Docker container version (Ubuntu 24.04)
> rednoise testing_rednoise.fft 


     Rednoise Removal Routine v2.0.1
                May, 2024

*** buffer overflow detected ***: terminated
Aborted (core dumped)

whereas the same file run through the previous version (v2.0) executes as expected with the correct output, e.g.,

# Bare metal install (Ubuntu 22.04), installed pre-meson build update
> rednoise testing_rednoise.fft


     Rednoise Removal Routine v2.0
            Feb, 2015


Done.  Rednoise removed from 4500000 of 4500000 points.

Apart from the difference in code between versions, the difference on our end is:

1. v2.0.1 is run in docker container, and was compiled with -march=znver3 -O3 included in the meson build w/ Ubuntu 24.04
2. v2.0 is being run on a "bare metal" install (installed a couple years ago though, so pre-meson method) w/ Ubuntu 22.04
