bring malloc() back to its initial state

Question

Do you know if there is a way to bring back malloc in its initial state, as if the program was just starting ?

reason : I am developing an embedded application with the nintendods devkitpro and I would like to be able to improve debugging support in case of software faults. I can already catch most errors and e.g. return to the console menu, but this fails to work when catching std::bad_alloc.

I suspect that the code I use for "soft reboot" involves malloc() itself at some point I cannot control, so I'd like to "forget everything about the running app and get a fresh start".

Only time I did something similar, we used our own allocator which would keep a reference to each allocated blocks. If we wanted to rollback, we would free all the allocated blocks and do a longjmp to restart the programme.
