Diagnostic cause compiler failure Unbound variable src/filters/renameVars.ml

[yuxiaomao]

Project: hashlink-debugger master (3e37095e)

Haxe: 7b92f74. Same error with 2106be4 (Juin).

Add var exc= before line 435 var excPos = jit.align.ptr * 5 + 8; gives a compiler failure in VSCode. But when disabled diagnostic, the failure does not exists anymore and show a normal error.
