The issue:
Thaumcraft's aspect generation, precisely the crucible one has a typo that restarts the recursion without keeping the history (thaumcraft.common.lib.crafting.ThaumcraftCraftingManager L576), causing an infinite loop.
Unfortunately, there's no easy fix for that, either replacing the class with a working version of it or creating a coremod to make the change dynamically.
