Truitt, can you attach the actual crash log?
I can't find any TestWebKitAPI (or other) crashes on the bot that line up with timestamps from this instance of the test crash: https://build.webkit.org/builders/Apple%20iOS%2011%20Simulator%20Debug%20WK2%20(Tests)/builds/6215
Truitt, is this still happening now that the bots are on iOS 12?
Yes, there is one logged api crash so far from the iOS 12 Release bots: https://build.webkit.org/builders/Apple%20iOS%2012%20Simulator%20Release%20WK2%20%28Tests%29/builds/26 Log: https://build.webkit.org/builders/Apple%20iOS%2012%20Simulator%20Release%20WK2%20%28Tests%29/builds/26
