When the fully static binary is compiled any IM invocation crashes in OpenPixelCache:

There are no issues with shared ImageMagick/MagickWand.

Crashes happen only with musl, there are no issues with Glibc https://github.com/ImageMagick/ImageMagick/issues/5964. The Linux static binary is now built with the Glibc toolchain.
