    * deactivated CHECK_ACTIVATION_COUNTS oer default
    * tested refcounts with Tcl 8.6b2, found bug in Tcl and submitted patch to sourceforge
 
+=============================================================
+Tcl 8.6b2 has a memory leak when re-bytecompiling procs. The cleanup-section in function TclProcCompileProc() (in file tclProc.c) iterates over "old" compiledLocals and frees it blindly (see below: ckfree(toFree)). However, the resolveInfo can contain data, and might point to to a deleteProc. i discovered the issue when using resolvers. The cleanup is handled correctly in TclProcCleanupProc() and in a similar way in InitResolvedLocals(). To ease maintenance one should factor out a common small c-function to handle the cleanup of compiled locals. The issue does not exist in Tcl 8.5.*. The following patch fixes the issue, and runs clean with valgrind.

+PS: i have submitted the bugreport already yesterday, but it did not show up so far. Maybe, there is something broken at sourceforge, so i try again. I hope, this will not generate a duplicate entry.
