[FATAL]
The compiler can handle about 400'000 lexical source tokens. A source token is either a number or an ident, e.g. 'int a[2] = {0,1};' contains the 12 tokens 'int', 'a', '[', '2', ']', '=', '{', '0', '1', '}' and ';'.
A source file with more than 400'000 lexical tokens.
Split up the source file into parts with less then 400'000 lexical tokens.
