patch 9.0.2129: [security]: use-after-free in call_dfunc() Commit: https://github.com/vim/vim/commit/a555069b7d790abedc60edc505bd35bda257949d Author: mityu <mityu.mail@gmail.com> Date: Sat Nov 25 15:41:20 2023 +0100 patch 9.0.2129: [security]: use-after-free in call_dfunc() Problem: [security]: use-after-free in call_dfunc() Solution: Refresh dfunc pointer closes: #13571 This Commit fixes a SEGV caused by a use-after-free bug in call_dfunc(). When calling check_ufunc_arg_types() from the call_dfunc() it may cause def functions to be re-compiled and if there are too many def functions, the def_functions array will be re-allocated. Which means, that the dfunc pointer in call_dfunc() now starts pointing to freed memory. So we need to reset the dfunc pointer after calling check_ufunc_arg_types(). Let's also add a test, to ensure we do not regress.
