Second statement: assign regex to $c

Inside regex: increment $c

what do you expect from an incremented regex?

Then your regex says greedy match ( any number  or  $c++ ) and number will match any time before trying the or branch.

Actually this might be the reason why incrementing a regex doesn't throw an error, it's never executed.
