Description
The std::getenv method may returns a pointer to NULL, hence assigning to std::string can lead to a memory leak in case that the environment variable does not exist. To make the code safe against memory leaks, a gammalib::getenv method should be added that catches the NULL pointers. The method should return an empty string in case that the environment variable does not exist.
Recurrence
No recurrence.
