aicasm: SIG 11 with 2.5.53 (new aic7xxx driver problem)

HI,
I was compiling new kernel 2.5.53.
If "build adaptec formware" option is enabled, (I know I should avoid it, but it
is a development kernel, and I am doing tests ;) ),
compiling aic7xxx driver,
compilation fails because
of a segmentation fault I get running aicasm.

Here is the error message:

yacc -d -b aicasm_gram aicasm_gram.y
