Synopsis: Segmentation fault with undocumented command line option

State-Changed-From-To: open->closed
State-Changed-By: rodrigc
State-Changed-When: Mon Dec 24 01:18:35 2001
State-Changed-Why:
    Does not occur in gcc 3.0.3.
    
    The version of gcc included with Red Hat 7.0 is pretty
    buggy.  Get the updates from Red Hat:
    http://www.redhat.com/mailing-lists/redhat-watch-list/msg00223.html
    
    In future, report bugs in the Red Hat version of gcc
    to Red Hat at: http://bugzilla.redhat.com/bugzilla/

 One thing this should have been reported to Red-Hat and I think there 
 is a
 new version from Red-Hat and it does not crash on the version of I have 
 installed:
 gcc version 3.1 20011221 (experimental)
 gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
 gcc driver version 3.1 20011221 (experimental) executing gcc version 
 3.0.4
 Thanks,
 Andrew Pinski

Default installation from CDs supplied with "Red Hat Linux 7 Bible" by Christopher Negus. IDG Books ISBN 0-7645-4778-X
>Description:
Initially used an hp makefile which included the (unknown?) option -Ae on the command line.  Even with simple "Hello world" source, compiler crashes with segmentation fault.

Compiler output (stdout + stderr):

cc -I. -Ae  -c hw.c
cc: Internal error: Segmentation fault (program cpp0)
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make: *** [hw.o] Error 1

Source (hw.c) is:

int main()
{
	printf ("Hello world!\n");
}

Command line is:

cc -I. -Ae  -c hw.c

(there are no header files, however)
>How-To-Repeat:

>Fix:
Remove the -Ae option.

Reported because your own documentation says a well-behaved compiler should not crash with invalid input.
