If the failure is on reading from the stack pointer, then it must be that some
caller misaligns the stack.  You have mentioned what target you're using, so it
is hard to guess what is faulty.  E.g. on i?86-linux stack must be 16-byte
aligned, if it isn't, you're violating the ABI (but gcc has some options where
you can ask it to realign the stack dynamically, or assume smaller alignment
etc.).
