It is undefined behavior to use `delete` expression on something which was not created with corresponding `new` expression. Switching to explicit global `operator delete()` call to match with `operator new()` call at `CGFunctionInfo::create()`. This issue is raised by Chromium ClusterFuzz, with ASan enabled. https://crbug.com/410141973 >From 15631133faed63a1c4bf7b3c9076629985e48bf9 Mon Sep 17 00:00:00 2001 From: mikit <37488201+m1...@users.noreply.github.com> Date: Tue, 15 Apr 2025 22:32:24 +0900 Subject: [PATCH] [CodeGen] Fix new-delete-type-mismatch in ~CodeGenTypes() It is undefined behavior to use `delete` expression on something which was not created with corresponding `new` expression.
