[Bug general/6490] New: memory leak in Environ.cxx?

jlong
frysk::sys::Environ::putEnvironment(jobjectArray envs)
{
  jstring* env_member = (jstring*)elements(envs);
  int envs_length = JvGetArrayLength(envs);
  new_environ = (char**)JvMalloc(sizeof(void*) * envs_length);
  for (int i = 0; i < envs_length; i++)
    {
      int sym_len = env_member[i]->length ();
      char *sym = (char*)JvMalloc(sym_len + 1);

the call JvMalloc allocates untracked memory from the heap (i.e., it is not
garbage collected).

Looking at Fork.java:

    public static ProcessIdentifier ptrace(File exe,
                                           String in, String out,
                                           String err, String[] args, String li\
bs) {
        Environ environ = new Environ();
        environ.setEnv("LD_LIBRARY_PATH", libs);
        long env = environ.putEnviron();
        return spawn(exe, in, out, err, args, env, PTRACE);

I don't see the memory being released.
