* generic/tclCompCmds.c (TclCompileUpvarCmd): Plugged a memory
leak in 'upvar' when compiling (a) upvar outside a proc, (b)
upvar with a syntax error, or (c) upvar where the frame index
is not known at compile time.
* generic/tclParseExpr.c (ParseExpr): Plugged a memory leak
when parsing expressions that contain syntax errors.
