// Exercises a bug reported by Michael Adjedj.
//
// In ecc/param.c, token_get() would increment a pointer past a terminating
// NUL, so the parser would keep attempting to read key/value pairs for a
// symbol table. If the memory after the string contains a duplicate key,
// then we have a memory leak because we strdup the value and misc/symtab.c
// overwrites existing elements during insert.
//
// Run with valgrind to spot the bug.
