Can you provide some details please?

Which version exactly? (Of CLSQL and SBCL)

How does it break? (Exact error message, backtrace, test-case that reproduces
this.)

Hello SBCL'ers,

How do I issue a context switch for the debugger.  For example, I issue 
the below and want to do a backtrace from the broken thread after it 
breaks.  Do I have to put a call to a backtrace function call in it?

(sb-thread:make-thread (lambda () (break)) :name "test")

The OpenMCL equivalent is:
(:y process-number)
:b

Many Thanks,
David

If you use Slime and *communication-style* :spawn, then this should
happen automatically. 

If working with a plain REPL, then you need to call 

 SB-THREAD:RELEASE-FOREGROUND

See:
