I can think of the following possibilities:

- The stack is getting adjusted by the wrong amount (i.e. the code with stack probes is subtracting a different total offset from the stack pointer compared to the code without probes).
- The code is trying to asynchronously unwind the stack (i.e. unwind while the stack probing loop is running), and there isn't a frame pointer.  This patch might need to be reworked a bit to support async unuwind.
