[ExM Users] OS X

[Tim Armstrong]

It looks like the message is coming from the Tcl memory allocator: it seems
like it's being asked to free something (the memory address 0x1018d6930)
that isn't a valid Tcl object - e.g. it was already freed, or it's just a
bad pointer.

Probably an invalid free or similar somewhere - possibly in the shutdown
code although it could be earlier in the ADLB code or user code.  You could
try running under valgrind to see if it provides more useful information.
If you have valgrind installed, it's just a matter of setting the
environment variable VALGRIND=valgrind for Turbine.
