Do you know exactly what the version of gcl is? I don’t see this problem 
on my gcl system, which also announces itself as

|using Lisp GNU Common Lisp (GCL) GCL 2.6.14 git tag Version_2_6_14 |

It’s possible I broke this since I was working on getting rid of global 
(special) variables in defint.lisp and other places a few months ago. 
But since I don’t see this issue with my gcl build, it will be hard for 
me to debug this.
