[pypy-dev] Identify this function

[M A]

for i in range(10000):
	print(i)

Hi, when I run this loop PyPy crashes at around 8800. Using a debugger I found out that this is the AARCH64 assembly function that has the crash. The arrow points to where the crash happens. I believe the crash happens one instruction before the arrow, at blr x17. X17 was set to a small number that was not a  valid address.

Would anyone know what the rpython version of this function is? Thank you.
