I was able to reproduce that bug on my system for a while. It turned out it was realated to #68799. Please update gcc-config and make sure that you are using the i686-pc-linux-gnu-3.4.3 gcc profile. Then do `unset GCC_SPECS` just to be sure, and try emerging memtest86+ again.

[Comment 2 Prakash Punnoor 2004-12-05 14:02:41 UTC]

To my big disbelief: It worked...

[Comment 3 Michal Januszewski (RETIRED) 2004-12-06 06:21:49 UTC]

In that case, I consider this bug to be fixed by the new gcc-config release. 

[Comment 4 César Fernández 2005-01-09 09:55:56 UTC]

Doesn't work for me.

** gcc-config -c = i686-pc-linux-gnu-3.4.3

[Comment 5 César Fernández 2005-01-22 17:49:37 UTC]

Again the same error as before with memtest86+ v1.50, same config.

I've no problems with memtest86-3.2. Maybe the + version needs the same patches used in the original version.

[Comment 6 Aurélien Francillon 2005-01-23 05:55:10 UTC]

I have the same problem here using a  hardened gentoo 
the flags -fstack-protecor -fPIC  must be filtred for pepole having it in their CFLAGS and 
for hardened gcc -fno-stack-protector and -fno-pic must be added.
This is really the same problem than on bug #66630
I'm joining a patch, really simmilar to the one from solar for memtest
i think this bug should be reopend ...

[Comment 7 Aurélien Francillon 2005-01-23 05:59:41 UTC]

Created attachment 49276 [details, diff]
patch enabling -fno-stack-protector and -fno-pic for memtest86+

against memtest86+-1.50

[Comment 8 Aurélien Francillon 2005-01-23 06:02:43 UTC]

Created attachment 49277 [details, diff]
makes the ebuid use the patch for ssp/pic

i dont know if "test_flag -fno-stack-protector && epatch ... " is needed as it
is  done in the ebuild of memtest86-3.2

[Comment 9 solar (RETIRED) 2005-01-23 07:03:48 UTC]

Bug is still present. Patches need to be added. But they also have to be reworked for 1.50. I'll hack on it and post here.

[Comment 10 solar (RETIRED) 2005-01-23 07:25:41 UTC]

Created attachment 49285 [details, diff]
memtest86+-1.50-hardened.patch

fstack has to be filtered on reloc.c also.
have fun fighting the dos format of the orig Makefile while trying to patch.

[Comment 11 solar (RETIRED) 2005-01-23 15:06:30 UTC]

Spock,
I you do not wish to make the changes yourself then feel free to reassign the bug to hardened@

[Comment 12 solar (RETIRED) 2005-01-23 15:07:03 UTC]

If you ^^

[Comment 13 Michal Januszewski (RETIRED) 2005-01-24 02:39:26 UTC]

Patch added to CVS. Thanks for your help :)

[Comment 14 César Fernández 2005-01-24 04:37:50 UTC]

WFM, thanks.
