Weird.  I remember there was troubles with certain versions where the
default statement couldn't access labels.  Might have been that one.
Either way, 3.11 is kind of old.  It seems to me like it could be
rather handy to try a newer version.  I know it's the latest "stable"
version, but, the only problems you'll find in a beta usually tend to
be minor annoyances rather than fatal errors.

You can find the beta versions here:

If the problem still occurs in them we'll know for certain something
is up.  If it doesn't and you have patience enough to keep writing to
a rewritable and testing the various versions, it'd probably narrow
things down more to find out just where the problem stops if it does
stop so you'd know just what changed.
