Nope, but it shouldn't be much work to get it working. In general,
SBCL and Allegro will always work correctly, because that's what the
developers use, and other implementations should be fine, but could
suffer occasional bit-rot in the details.

Well that error isn't too surprising. Could you set *debug-tk* to t
and try again? Also, please interrupt ECL when it's hung and post a
backtrace from there.

If an SBCL change ever breaks Ltk it should get addressed very, very quickly.
