Re: ‘void free(void*)’ called on unallocated object ‘yyssa’ [-Wfree-nonheap-object]

Hi Akim,
you were right, the #if 0 part was added by a script to work around a
compiler warning. When I regenerated the code with Bison 3.7.4, it was
no longer necessary.
Currently I try to get my changes included into CMake upstream. Once I
did that, I am going to come back to your other idea on improving the y
file.

Thanks!
Christoph
