; This test ensures that catch parameters are not instrumented on Windows.

; This file was generated using the following source
;
; ```C++
; #include <exception>
; #include <cstdio>
;
; int main() {
;  try {
;   throw 1;
;  } catch (const int ex) {
;   printf("%d\n", ex);
;   return -1;
;  }
;  return 0;
; }
;
; ```
; then running the following sequence of commands
;
; ```
; clang.exe -g0 -O0 -emit-llvm -c main.cpp -o main.bc
; llvm-extract.exe -func=main main.bc -o main_func.bc
; llvm-dis.exe main_func.bc -o main_func_dis.ll
; ```
; and finally manually trimming the resulting `.ll` file to remove
; unnecessary metadata, and manually adding the `sanitize_address` annotation;
; needed for the ASan pass to run.
