FIXED: "USE BEFORE" is seen to generate SIGSEGV

[Simon Sobisch]

Thanks for the error report.

Ron worked on this in trunk (4.x) last week (revisions 4233,4234,4238),
the changes were merged to 3.2-development and the final fix merged back
today. It now raises one error message because of the undefined
identifier and goes on parsing as expected.
