Greetings
Just a quick arm wave to see if I have the logic right.
In a redundant environment when both sets are corrupt, the env_init function sets the environment data pointer to the default data. If this is then added to by the fw_setenv function, the memory overwritten is not the calloc'ed space that is big enough to hold the extra data but the initialised memory of the program that contains the defaults! Methinks that the defaults should be memcpy'ed into the calloc'ed space.
I've not looked at the non-redundant env case.
