Summary: ARGVx is not reset in recursive function calls
Description:
When recursively calling functions, ARGV0-ARGV9 are inherited by the inner
function calls - this will make it hard to decide for the inner function calls
to decide whether they got an argument or not.
Steps to Reproduce:
run the following code:
function(testfunc1)
message(STATUS "testfunc1: ${ARGV0} ${ARGV1} ${ARGV2}")
testfunc2("${ARGV0}")
endfunction(testfunc1)
function(testfunc2)
message(STATUS "testfunc2: ${ARGV0} ${ARGV1} ${ARGV2}")
endfunction(testfunc2)
testfunc1(para1 para2 para3)
expected result is
L:\>cmake -P C:\kde\kde-stable\tmp\cmake-argv-bug\argv-bug.cmake
-- testfunc1: para1 para2 para3
-- testfunc2: para1
actual result is
L:\>cmake -P C:\kde\kde-stable\tmp\cmake-argv-bug\argv-bug.cmake
-- testfunc1: para1 para2 para3
-- testfunc2: para1 para2 para3
Additional Information:
ARGN works as expected;
It is unclear whether anybody could rely on this bug, since it likely depends on
the order in which functions are called.
