data/pcg-cpp-0.98.1/include/pcg_extras.hpp:197:12: [3] (random) setstate:
This function is not sufficiently random for security-related functions
such as key and nonce creation (CWE-327). Use a more secure technique for
acquiring random values.

Statically-sized arrays can be improperly restricted, leading to potential
overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
functions that limit length, or ensure that the size is larger than the

Unless checked, the resulting number can exceed the expected range

input had no minus sign (large numbers can roll over into negative number;
consider saving to an unsigned value if that is intended).

data/pcg-cpp-0.98.1/include/pcg_random.hpp:1365:18: [1] (buffer) equal:
Function does not check the second iterator for over-read conditions
(CWE-126). This function is often discouraged by most C++ coding standards
in favor of its safer alternatives provided since C++14. Consider using a
form of this function that checks the second iterator before potentially
overflowing it.
