<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: None (smanna12) <details> <summary>Changes</summary> This patch adds a null check for InstantiatedFrom to prevent dereferencing a null pointer during the template instantiation process in clang::Sema::SetupConstraintScope(). The fix ensures that the function exits early with an appropriate error if the InstantiatedFrom pointer is not valid. --- Full diff: https://github.com/llvm/llvm-project/pull/97913.diff 1 Files Affected: - (modified) clang/lib/Sema/SemaConcept.cpp (+3) ``````````diff diff --git a/clang/lib/Sema/SemaConcept.cpp b/clang/lib/Sema/SemaConcept.cpp index 202dd86c67f62..353276e9b2802 100644 --- a/clang/lib/Sema/SemaConcept.cpp +++ b/clang/lib/Sema/SemaConcept.cpp @@ -636,6 +636,9 @@ bool Sema::SetupConstraintScope( ?
