Are you still getting this issue?

Could you check the address at the top of the stack? i.e. use

show registers

to know the value of esp, say 0x2f0094, and use

examine 2f0094

for instance, to get the value. Also, you could add

        popl %edx
        pushl %edx

just before the ret, to determine whether the issue is the stack itself
or the return address.
