Bug 84407 – sys-devel/gcc-3.4.3.20050110: -fstack-protector in CFLAGS causes failure to merge

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description FieldySnuts 2005-03-07 08:52:20 UTC]

sys-devel/gcc-3.4.3.20050110 will not finish merging if -fstack-protector is in CFLAGS.

I was able to cause this failure three times. Interestingly, the error was the same, but came from a different application. Here are the three failures in order:

 cc1: error: unrecognized command line option "-fstack-protector"
 Second time: I passed my CFLAGS without -fstack-protector to emerge on the shell. I later was told this didn't do anything, anyway. Same error as above.

 Third time: Same as second time. However, the error was different: cc1plus: error: unrecognized command line option "-fstack-protector"

Editing make.conf and removing -fstack-protector there allowed me to complete the merge the first attempt.

So I'm no programmer, but perhaps this needs filtered out?

NOTE: I apply different flags via package.use, that line is:

sys-devel/gcc boundschecking    -gtk

Note: I just changed my account and email address.

I'm not sure if it's related, but I just saw an odd problem with the same error with media-sound/alsa-tools-1.0.8-r1.

I received the error

 cc1plus: error: unrecognized command line option "-fstack-protector"

And I'm not sure why. I do not have -fstack-protector in CFLAGS.

Can you please provide the emerge log which shows this?  Can you try switching to the vanilla gcc profile (using gcc-config) and emerge the new gcc?

[Comment 4 FieldySnuts 2005-03-10 15:39:24 UTC]

I no longer have the merge log, i finished rebuilding my system.

Do you still want me to try the bit with vanilla?

[Comment 5 Jeremy Huddleston (RETIRED) 2005-03-10 16:00:42 UTC]

Are youo able to trigger the bug still?

[Comment 6 FieldySnuts 2005-03-10 16:13:25 UTC]

Well i'm not sure why but this version of gcc, gcc-3.4.3.20050110 , doesn't even recognize -fstack-protector. Not sure if I missed a USE flag? I would like to have that back.

I removed -fstack-protector from my CFLAGS in make.conf because of this.
