Still don't have a trace. However, enabling `FRG_SLAB_TRACK_REGIONS` causes the following assertion to fail: `/sysroot/usr/share/mlibc-build/frigg/include/frg/rbtree.hpp:213: Assertion 'grand && h(grand)->color == color_type::black' failed!` This is due to `h(grand)->color` being `color_type::red`

Was an issue with my virtual memory manager that only happened under very specific circumstances.
