But:

int clearenv(void)
+{
+       extern char **environ;
+       char *var;
+
+       while((var = environ[0])) {
+               var = bb_xstrndup(var, strcspn(var,"="));
+               unsetenv(var);
+               free(var);

Hmm. I think, you call free() as double usage (from unsetenv too).
