memory leak in ItclCreateArgList function

Sure looks like this was fixed more than 2 years ago. Upgrade to fix. https://core.tcl-lang.org/itcl/info/0b0d0e0b8cd8105c

That said, the routine ItclCreateArgList() in current development certainly includes ckfree() calls on both argv and defaultArgv. Can you specify the code path that misses those calls and leaks?

~~~ All work on Itcl 4.0.* is abandoned. Upgrade to Itcl 4.1.2 or development trunk.

Once I set up a testbed with all those outdated releases on an OSX High Sierra system, my testing shows no failure running the test script. Sorry, but there continues to be nothing I can do when I cannot reproduce the failure.

When an ItclMemberCode improvement is done, we'll want you to try it and determine how much it helps you.

Looks like the next low-hanging fruit in preserve elimination is ItclMemberCode. Give it a proper refcount as we've done with several other structs now.

Sorry, no. At base that implementation also calls Tcl_Preserve.
