monero-wallet-rpc Wallet initialization failed: std::bad_alloc

[got3nks]

After upgrading to v0.10.1 I can no longer load a wallet created with simplewallet (v0.9):

monero@server:~$ /home/monero/monero-wallet-rpc --rpc-bind-ip=0.0.0.0 --rpc-bind-port 8082 --password xxx --wallet-file /home/monero/wallet.bin --daemon-address=127.0.0.1:18081

Just restore your wallet using seed or private key into new wallet file via monero-wallet-cli.

This is caused by an incompatible wallet cache. If you delete the cache (<wallet>) you should be able to open the wallet created with simplewallet. If that doesn't work, use the method described by @gituser.

So this is most likely caused by a crazy allocation request when trying to parse in the new invalid format. Does the existing cache format have a header that can be used to identity between types? So that the code doesn't try to blindly attempt to parse the wrong format?
