I tried downgrading dejagnu, expect, tcl, and tcllib to the versions IIRC I 
did not have this problem with, but it persists even with them :(, and besides 
the "new" versions are pretty much plain rebuilds of the earlier ones, except 
tcl which went from 8.5.6 to 8.5.7.  bash version doesn't seem to matter 
either.

Maybe this is what you meant above put in other words, but removing the "-re 
{a\\\'b/c} {" block from compgen.exp or hacking the regexp so that it does not 
match makes the problem go away for me.  I don't think that's the correct fix 
at all, but my tcl/expect-fu is not good enough so it'd make sense for me to 
try to dig deeper.
