:-) I think I saw Mark submit a patch maybe a year ago that really
required the token "0" to indicate that a function is abstract. I
have a hard time understanding why anyone would use anything different
anyway, but that may be beyond the point...

: Search converges between 2003-12-17-trunk (#430) and 2003-12-18-trunk (#431).
Hmm that is the normal date for this ICE :)
This only happens with checking turned also.

Anybody has an --enable-checking version of 3.4? I assume the bug is present
also there.

Giovanni's right: it also ICEs with an --enable-checking'd 3.4:
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
x.cc:1: internal compiler error: tree check: expected identifier_node, have
integer_cst in c_parse_error, at c-common.c:5893
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Giovanni, you may want to apply your patch there as well.

Isn't this just a matter of not filling ridpointers with null_node
as done below? Whenever RID_NULL is encountered, we return just
null_node anyway, and there are apparently no other places where
ridpointers[RID_NULL] is read. I'll test this patch, let's see if
this helps.

Maybe. But cp_parser_error is stil buggy and will ICE on other keywords (e.g.
"public"/"protected"/"private") so thinking that is still desirable anyway.
I'll get back to this bug later next week when I'm through with the finals.

Patch needs update and splitting. The hunks to cp_parser_pure_specifier and to
decl.c are safe and can be submitted separately as a way to improve/fix the
error message here.
The patch to cp_parser_error requires to be rewritten by taking into account
how each keywords is identified in source code.

The cp_parser_pure_specifier and decl2.c hunks are OK, and I think will be
sufficient to fix the PR. Please apply.

I tested this again and seems fixed on the mainline, is there a reason why it is still marked as 4.0
regression?
