Okay something very wierd hash related is going on here:
If I evaluate:
(progn
(describe-buffer-bindings (current-buffer))
(require 'comp)
(make-comp-data-container))
I get
#s(comp-data-container nil #s(hash-table test tab-bar--auto-width-hash-test))
In place of the expected
#s(comp-data-container nil #s(hash-table test comp-imm-equal-test))
Adding Mattias in Cc.
Thanks
Andrea
