Summary: Mem leak when getting error

Initial Comment:
If I repeat this:
  interp create testinterp
  catch {testinterp eval {lisx}}
  interp delete testinterp

memory increases with each iteration.
According to [memory info] 25 packets,
709 bytes, is lost each iteration.

If I replace "lisx" with "list" so no
error occurs, nothing leaks.

testinterp eval {catch lisx}

leaks as well

This is run with current CVS HEAD
on a WinXP machine.

Change back to "lisx"
and define [proc unknown args {}]
in testinterp and the leak also
goes away.

Change "lisx" to "error foo" and
the leak goes away.  Thus, I suspect
the [unknown]/auto-loader instead
of [return]/$::errorInfo.

Oh my, leak confirmed in current HEAD under linux, no
MEM_DEBUG (*). It is not present in 8.4.5.

(*) method: infinite loop 
 while 1 {
     interp create testinterp
     catch {testinterp eval {lisx}}
     interp delete testinterp
     after 100
 }
watched in top.
