The int counter in the main loop was uninitialized, so we might end up
looping a very large number of times before completing successfully.
I suspect that was unintended, so I'm adding a zero initializer.
Tested on x86_64-linux-gnu, with a cross to ppc-vx7r2, where we had 'i'
assigned to a register that inherited a negative value close to
0x80000000. I'm installing this as AFAICT obviously correct. Jakub,
please let me know otherwise. May you and your family have a Happy
Easter.
