-t4 broken (r34808)

[coke]

Running a tcl program, I get an error like so:

Method 'get_list' not found for invocant of class 'String'

Running this through parrot -t4, the error changes to:

No such attribute '$.target'

I already fixed this once; perhaps there's another attribute that needs to get saved/restored on the interpreter when tracing.

with a recent partcl and parrot 39187:

$ ~/bird/bin/parrot -t4 tcl.pbc t/cmd_array.t 
# Calling sub 'tcl;_main'
# (null)
# Calling sub 'parrot;TclExpr;PAST;Grammar;__onload'
# current instr.: '_main' pc 3 (src/tclsh.pir:37)
Segmentation fault

Removing the -t4, you get the tcl prompt.

This no longer occurs with a parrot of the 2.1.0 vintage.
