Infinite loop when counter overflows

[lukasz.czajczyk@…]

Hi,

In function bool perl_matcher<BidiIterator, Allocator, traits>::match_dot_repeat_slow()

variable 'count' can overflow since it's defined as unsigned int and rep->max is std::size_t initialized to numeric limits max.

while(count < rep->max) {

pstate = psingle; if(!match_wild())

break;

++count;

}

On Red Hat 6.7, 64 bit, unsigned int it 32 bit while size_t is 64 bit.
