patch 8.2.2188: Vim9: crash when calling global function from :def function Commit: https://github.com/vim/vim/commit/cd45ed03bfdd7fac53d562ad402df74bd26e7754 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Dec 22 17:35:54 2020 +0100 patch 8.2.2188: Vim9: crash when calling global function from :def function Problem: Vim9: crash when calling global function from :def function. Solution: Set the outer context. Define the partial for the context on the original function. Use a refcount to keep track of which ufunc is using a dfunc. (closes #7525)
