I misread your gdb display. I'm used to using the i r command to look in
the registers.

You used the x/x command, which shows the contents of the register, then
what it is pointing to.

So the values in ebp and esp DO look reasonable. That's the range I
expect in 32-bit program, and they are reasonably close to each other.

I apologize for my error.

From what you have posted, I don't see any problems with the first few
instructions. So I have no idea why the program is crashing there.

Sorry...
