Description
In some cases, clang-repl doesn't recover correctly from input errors, resulting in a state where unexpected linker errors can happen in correct statements given afterwards.
It seems that this kind of error occurs only with "pow".
Reproducer (I ran it with the LLVM 20 packages in NixOS):
LLVM (http://llvm.org/):
LLVM version 20.1.6
