   1 // Exercises a bug reported by Michael Adjedj.
   2 //
   3 // In ecc/param.c, token_get() would increment a pointer past a terminating
   4 // NUL, so the parser would keep attempting to read key/value pairs for a
   5 // symbol table. If the memory after the string contains a duplicate key,
   6 // then we have a memory leak because we strdup the value and misc/symtab.c
   7 // overwrites existing elements during insert.
   8 //
   9 // Run with valgrind to spot the bug.
