Re: [PATCH 0/5] glr.cc: support syntax_error exceptions

Hi.

>I'll push these commits to master once the CI validates them

Thanks a lot for this fix. Unfortunately, it seems it is buggy.

I tested it on that code from paste.gg (I attached the code here in case that 
paste.gg paste disappears). Command line is same:

    flex -o lex.yy.cpp scanner.lpp && bison -do parser.tab.cpp parser.ypp && 
g++ lex.yy.cpp parser.tab.cpp && echo 2 + 2 | ./a.out # Should print 4

And your patches work. But when I type this:

    echo 2 + % | ./a.out

I see this:

    Invalid character: %
    syntax error: unexpected $undefined, expecting NUMBER or '('

But if I replace %skeleton "glr.cc" with %skeleton "lalr1.cc", I see this:

    Invalid character: %

So, it seems that now syntax_error support in glr.cc is inconsistent with 
lalr1.cc .
