Bug Report in 'gcc' While Compiling 'ddd'

[David Ballantyne <dballant at math dot ualberta dot ca>]

Hi, I have some bad news.

Of course, you're probably expecting it.  Yup:  a bug.

I was compiling 'ddd' on an Alpha using gcc 2.95.2, and gcc blew a
gasket on the file 'HelpCB.C'.  The same error _did not_ occur when no
optimization flag was set.  That is to say, compile without the '-O1'
flag, and this thing works. 

So, enough with the preliminaries, the bzip2'ed '.ii' file is attached
and here's the standard command line output:


# gcc -v --save-temps -DHAVE_CONFIG_H -DNDEBUG -O1 -g -W -Wall
-trigraphs -c -I. -I. -I./.. -isystem /usr/X11R6/include -o HelpCB.o
