core dump in 8.5.4 using SQLite ... more info

I'm having difficulty with SQLite 3.6.1 and Tcl 8.5.4, essentially the script runs to completion, correctly I might add, but upon termination, I get a core dump on FreeBSD 7.0Release. Tcl 8.4 has no such problems with the same script.
I rebuilt tclsh using the following configure script (to retain the symbols, and I include both the script and the gdb traceback ...
../configure --enable-shared --enable-symbols --disable-threads)
It appears that Tcl is attempting to "unload" the libtclsqlite3.so library upon termination, and stumbles ... Has anyone seen this behaviour?? Oh, and an explicit unload of the library file fails with a message;
file "/usr/local/lib/libtclsqlite3.so" cannot be unloaded under a trusted interpreter
while executing
"unload /usr/local/lib/libtclsqlite3.so "
The traceback shows that TclEvalObjvInternal appears to be called from TclExecuteByteCode with some bad arguments. Surely this can't be good.
Am I doing something wrong??
