free(): Invalid pointer when specifying bool flags on program finish

[0sleep]

I have a program parsing some required options, some optional options, and I'm trying to also check if some flags are set. From what I understand, I need to:

• initialise a bool like bool testBool = false
• add option to parser like | lyra::opt(testBool)["-t"]["--testbool"]("Test bool");
  After this, I can then parse argc and argv, and check for testBool being passed like if (testBool) { std::cout << "TestBool = y" << std::endl; }
  However, if I have any bools in my lyra arg parser, my program seems to work fine until my main function returns, after which I get

free(): invalid pointer
Aborted: core dumped

if I pass -t to my executable.
Does anyone else experience this issue? (There is a decent chance that this is not actually a problem with lyra itself, but maybe a problem with my c++ skills, I am very new to this lang)

I'm fairly sure this is not a problem in Lyra. But hard to tell without a minimally full example program. The Lyra code gets checked with an address sanitizer which would catch such memory errors (limited to the tests and examples). Try using such an address sanitizer yourself to see if you can find the problem.
