OK, the external script is definitely guilty. However, it is buggy and triggers the Squid assertion failure only in specific circumstances. So it's trasaction-specific. In my use case I would definitely prefer that only a few transactions were "killed", and that the whole of the proxy service would keep working.
Of course, I would still need to identify these cases and fix them, but in the meantime I would not get a general crash.
On the other hand a general failure forces me to look into this issue with greater celerity. ;-)
