Subject: Fixed an internal compiler error when the first token of a source file
X-Git-Tag: V2.12.0~1374
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=7596da75f024b9c6e74735d60bff847ca173483a;p=cc65

Fixed an internal compiler error when the first token of a source file
caused an error message. In this case, the line info was not available
leading to a PRECONDITION VIOLATED.
