Interesting... this crash doesn't seem to happen on the Mac port. I'm not sure what would be different about the GTK build? Is it possible to figure out what line in mapProtoFuncSet we are crashing on? (In reply to Keith Miller from comment #1) > Interesting... this crash doesn't seem to happen on the Mac port.

I could not get a proper backtrace, but it's consistently crashing accessing the string content in the first iter->key() when rehashing a map right after inserting the key "http://localhost:8800/html/semantics/scripting-1/the-script-element/module/evaluation-order-4.2.mjs". (e.g. asString(iter->key())->length() is enough to crash). |
