Bitcode file that exhibits this behaviour

Currently on Windows, `opt -verify` crashes even on simplest
input, like the code generated from

int main() {
  return 0;
}

Example:

$ llvm-gcc --emit-llvm simple.c -o simple.bc -c

$ opt -verify simple.bc
Stack dump:
0.      Running pass 'Function Pass Manager' on module 'simple.bc'.
1.      Running pass 'Module Verifier' on function '@main'
