I created a custom SOP. Sometimes I can cook it successfully, other times it segfaults. It seems to always segfault after the "cookMySop()" function completes (i.e., outside of the code that I wrote???). When it segfaults, it either gives me one of two error logs, or no error log at all. Here are the two error logs. Can anyone make sense of them and direct me in a direction that I can start to look to debug this?
