Hi,
the new backtrace code is in. If a parrot program aborts due to an error, a
backtrace is shown. Examples:
----
Null PMC access in invoke()
current instr.: 'd' pc 149 (t/op/debuginfo_4.imc:24)
called from Sub 'c' pc 116 (t/op/debuginfo_4.imc:18)
called from Sub 'b' pc 85 (t/op/debuginfo_4.imc:13)
called from Sub 'a' pc 54 (t/op/debuginfo_4.imc:8)
called from Sub 'main' pc 23 (t/op/debuginfo_4.imc:3)
----
Null PMC access in invoke()
current instr.: 'rec' pc 111 (t/op/debuginfo_8.imc:12)
called from Sub 'rec' pc 71 (t/op/debuginfo_8.imc:8)
... call repeated 90 times
called from Sub 'main' pc 24 (t/op/debuginfo_8.imc:2)
----
maximum recursion depth exceeded
current instr.: 'main' pc 21 (t/op/debuginfo_7.imc:2)
called from Sub 'main' pc 21 (t/op/debuginfo_7.imc:2)
... call repeated 999 times
----
Lexical 'nosuchlex' not found
current instr.: 'Test2 :: foo' pc 35 (t/op/debuginfo_6.imc:10)
called from Sub 'Test2 :: main' pc 25 (t/op/debuginfo_6.imc:5)
If you use "debug 1", a backtrace is shown even for exceptions cought with an
exception handler.

PS: filenames are still wrong for included files, because only one filename
is stored per bytecode segment (AFAIK). Cf. src/sub.c:615ff
