Hello,

This is on Windows 10 and ABCL 1.4.0.  I use the library Vecto as an example.

When I start ABCL in a command window, I can load Vecto using asdf or ql.

If I do the same from Slime (2.18), I get a java stack overflow:

Stack overflow.
   [Condition of type STORAGE-CONDITION]

Restarts:
 0: [*ABORT] Return to SLIME's top level.
 1: [ABORT] Abort thread.

I have several other issues with ABCL (running from command-line) such as uiop's run-program, loading cffi.  
I have reported them on the asdf and abcl lists.  I am not sure if there is a common thread in all.
