1172,Lexical Associations Not Thawed with Tailcalls,chromatic,,"From t/pmc/exception.t test #26:

.sub main :main
.local pmc a
.lex 'a', a
a = new 'Integer'
a = 42
push_eh handler
exit 0
handler:
.tailcall exit_handler()
.end

.sub exit_handler :outer(main)
say ""at_exit""
.local pmc a
a = find_lex 'a'
print 'a = '
say a
.end

When run as PIR, the output shows that a is 42. When compiled to PBC and run 
from PBC, this produces:

at_exit
a = Null PMC in say
current instr.: 'exit_handler' pc 24 (t/op/exceptions_23.pir:17)

Remove .tailcall, recompile to PBC, and you get the correct answer.
