	First error, if any.

Detailed Description

Latches the first builder error so a program can be transliterated linearly.

On error every subsequent expression receives a dummy 0.0f; the resulting cascade errors are ignored because only the first is reported. The inputs are static, so any latched error is a Donner bug surfaced by the golden test, never a runtime condition.
