Memory leaks when importing problems #93
Description
It seems that the allocated memory (or maybe a portion of it) is never released after a problem is imported.
If I run the following code, the memory usage monotonically increases as the memory allocated for each problem imported is not deallocated. The program consumes several gigabytes of RAM (~8 GB if I skip ~30 problems that take longer times to get imported) by the time it reaches the end of the loop.
import pycutest
prob_list = pycutest.find_problems()
for prob_name in prob_list:
prob = pycutest.import_problem(prob_name)
I use PyCUTEst 1.7.1 on macOS 14.4 with Python 3.9.13.
I saw similar issues reported before. I don't know if it's possible to be fixed since threads on the other issues mentioned this comes from upstream CUTEst or from memory leaks in Python/NumPy.
