Akim Demaille 66ed97537a deterministic test suite. 
Some consistency checks on symbols are performed after all the
symbols were read, by an iteration over the symbol table.  This
traversal is nondeterministic, which can be a problem for test
cases.

Avoid this.

Addresses another form of nondeterminism reported by Joel E. Denny.
