Do away with the flaky free_work api in the driver code which would often lose the work data in opencl and simply flush it before exiting the opencl scanhash.

Track all dynamically allocated memory within the work struct by copying work structs in a common place, creating freshly allocated heap ram for all arrays within the copied struct.
...
Clear all work structs from the same place to ensure memory does not leak from arrays within the struct.
Convert the gbt coinbase and stratum strings within the work struct to heap ram.
This will allow arbitrary lengths without an upper limit for the strings, preventing the overflows that happen with GBT.
