The first time the crash appeared I had 7.3.6 but it persists in 7.3.8. It happened to two developers with separate configurations. This crash is of the sort that appears randomly, is reproducible for some short time and then goes away. Our application is using Nette Framework with Tracy debug bar and I traced the crash to this particular line: https://github.com/nette/tracy/blob/8b6796afb25fb92e070d4ef7055a8f64e3c47bc1/src/Tracy/Dumper/Dumper.php#L491 Disabling some Tracy panels resolved the problem but also adding some nonsensical line before the aforementioned line did.
