The contents of several registers don't look like typical data pattern but like ARM instructions. These could either be there from the copy operations or from improper initialisation of the stacks or C runtime library. Especially R0 looks like code but LR can be code, too. LR should always contain an address of valid code memory; otherwise it really look like a stack corruption. So please check your stack initialisation and sizes.
And you are aware that variables with function scope are being put on the stack and not on the heap, are you?
I recommend picking a proper JTAG debugger and steps through your initialisation code.
