UndefinedBehaviorSanitizer: DEADLYSIGNAL

Question

Я работал над набором задач 4 в CS50, этот код хорошо скомпилирован; однако, как только я запустил его, он полностью сломался и выдал мне следующее сообщение об ошибке:

UndefinedBehaviorSanitizer:DEADLYSIGNAL
==13838==ERROR: UndefinedBehaviorSanitizer: SEGV on unknown address 0x7fae6282690a (pc 0x0000004292c7 bp 0x7fff28e4e760 sp 0x7fff28e49530 T13838)

UndefinedBehaviorSanitizer can not provide additional info.
==13838==ABORTING   

Во время моей работы с предыдущими фильтрами ошибки не появлялись, и все работало хорошо, так же, как я реализовал этот новый код, это дало мне эту ошибку. Я попытался заменить 0 на 1, чтобы автоматически получить доступ к первому пикселю и т. Д .; однако это не сработало, и я полагаю, что это не правильно; поэтому я возвращаю его к 0. Я был бы благодарен за любую помощь. Большое спасибо.
