### Prerequisites

- [x] I have written a descriptive issue title
- [x] I have verified that I am using the latest version of ImageMagick
- [x] I have searched [open](https://github.com/ImageMagick/ImageMagick/issues) and [closed](https://github.com/ImageMagick/ImageMagick/issues?q=is%3Aissue+is%3Aclosed) issues to ensure it has not already been reported

### Description
<!-- A description of the bug or feature -->
There's a heap-buffer-overflow in MagickCore/fourier.c:299:18 in ComplexImage, and I compiled the lasted version with --disable-openmp option.

### Steps to Reproduce
<!-- List of steps, sample code, failing test or link to a project that reproduces the behavior.
     Make sure you place a stack trace inside a code (```) block to avoid linking unrelated issues -->
run cmd:
`magick -seed 0 -mattecolor rgb"("225,230,14")" -debug Configure "(" magick:wizard +repage ")" "(" magick:netscape +repage ")" -fuzz 82 -caption "j$Y%Be" -blue-primary 727,475  -crop 405%-43-16 -crop 832x886>+11-13 -complex magnitude-phase   tmp`

and also this command
`magick -seed 0 "(" magick:netscape +repage ")" "(" magick:wizard -resample 24x44 -resample 47x83  ")" "(" magick:netscape -charcoal 4 -random-threshold 42x71 -shade 81x21  ")" -complex magnitude-phase   tmp112
`

Here's ASAN result.
