The problem is not in the code, but in the test should_pass_a_number_of_edge_assertions. When enter the string "aa", get the output {"aa"}, when enter "aaaab" : get {"aaaab", "aaaba", "aabaa", "abaaa", "baaaa"}, as required by task, but this test it's throwing an exit code of 139. If I can send the code, please check it.

(C++) Exit code 1. My code does not pass random tests. The problem is in kata itself, since when checking in the MVS and in sample tests, substituting the same input, the correct answer is obtained at the output. Kata just picks up and doesn't move the first symbol:
Expected: equal to OMyrWsRXDYdURBmjnay !
Actual: nOMyrWsRXDYdURBmj ay !
In MVS and sample tests (input: nOMyrWsRXDYdURBmj !) Actual: OMyrWsRXDYdURBmjnay !
Fix pls.
