Line 8 of asmLex.l is your redefinition of input().  Such redefinition
is an officially unsupported (i.e. non-standardized) hack in original
lex, and not supported at all by flex.

Get rid of that input() override and you might be getting somewhere.

If you keep getting parse errors, you'll have to investigate the
actual produced C source code, or even a preprocessor dump of it.
