Summary0013387: ARGV1 scope leak
DescriptionARGV1 values can leak into sub functions if they are optional arguments.
Steps To Reproducecmake_minimum_required(VERSION 2.8)

function(bar arg)
  set(bar_arg ${ARGV1})
  message("bar_arg=${bar_arg}")
endfunction()

function(foo arg)
  set(foo_arg "${ARGV1}")
  message("foo_arg=${foo_arg}")
  bar(${arg})
endfunction()

foo(dummy dummy2)

========

bar() was called with 1 argument, not 2. But the ARGV1 from foo() leaked into the ARGV1 of bar().
