The \u0027:N\u0027 branch parses the number with `atoi(src)` and assigns it to the binder counter with no range check, so a statement containing \u0027:2147483648\u0027 leaves the counter negative (-2147483648 with glibc, where atoi wraps). Each following \u0027?\u0027 then expands through `sprintf(start, \":p%d\", idx++)` to \u0027:p-2147483648\u0027, 14 bytes with the terminating NUL where the buffer budgets 7. The placeholder limit added in 1.650 tests the counter against 99,999, which a negative counter passes.\n\nAny caller that preparses an untrusted statement into \u0027:pN\u0027 style placeholders gets a heap out-of-bounds write that grows with the number of \u0027?\u0027 marks following the poisoned placeholder. The \u0027?\u0027 and \u0027%s\u0027 return styles compare the parsed number against the expected sequence and error out, and are unaffected."
