It seems as if your C code has a bug. You allocate an array of limit == 255 elements for table array. These elements would be indexed from 0 to 254. But you set 
table[limit] = 0;

which stomps on the memory location just after the end of the array. The bug would be fixed by mallocing an extra element: 
char *table = (char *) malloc( (limit + 1) * sizeof(char) );

Happily, Perl does not have these sorts of problems.
