Description dje 2010-08-18 20:13:46 UTC 
bash$ ./gdb -nx
... 7.2.50.20100816-cvs ...
(gdb) set lang objective-c
(gdb) p 1.1f
Invalid number "1.1f".

The problem is in yylex.  It flags the number as invalid before calling 
parse_number.

I think objc-exp.y should be merged with c-exp.y.
That would fix this problem plus a bunch of others -- anything else
that was fixed in c-exp.y in the past several years.

This bug is now obsolete.

After objc-exp.y was merged with c-exp.y that left the objective-c language support broken, but now it has been fully restored by the following patch:

As noted, this was fixed a long time ago.
