crashing cc1 - merry christmas :)

[Cedric Roux]

Hello dear gcc coders,

I was experimenting with data structures for my little
ctl formulas parser (yes, I know, everyone uses some lex/yacc
facility, but well, you know...) and I found a little error in
gcc.

I didn't test it against a 3 release, I unfortunatly don't
have one under my hand. Sorry if this problem does not exist
in this version anymore.

check this :
/users/cao/cedric/bdd/ctl>uname -m    
i686
/users/cao/cedric/bdd/ctl>gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs

/users/cao/cedric/bdd/ctl>cat toto.c
int x = (int [2][]){0};
/users/cao/cedric/bdd/ctl>gcc -c -Wall toto.c

(Yes, it's a redhat version, but read the following :).)

cc1 gives a nice segmentation fault.
Of course the program has no meaning at all, but gcc should
not give a segmentation fault. It should say "syntax error"
or something similar. (A one-line program to crash cc1, it's
my second one, I think I will open a contest one of those days :))))

I tried this against gcc 2.95.2 on a silicon graphics/indy,
with an egcs release under a sparc station, and it crashes too.

So, well...

Sorry, I have not much time to investigate the source code, so I let
you do (if there is still a problem in your current release).

I wish you a merry christmas ! :)

Cedric.

PS: excuse my horrible english.
