Re: Problem with running tests during installing coreutils-5.94

Hi everyone,

I am positively suprised by the number of suggestions I have received,
thank you very much :-)!
Here is my combined response.

>>> No stack.

My previous gcc settings were: -g -O2
I have changed it to: -g
But the results were exactly the same.
I have also received a suggestion to try with newer gcc, I was using
gcc 3.3.6 previously.
I tried with gcc 3.4.5, but also without any difference.

This is the error message I have in kernel log, not very helpful :-):
Apr 18 14:05:29 [kernel] Unable to handle kernel NULL pointer dereference at
virtual address 00000018
Could anything be done to help me not to rebooot the server every time?

Finally I have  applied patch from Paul Eggert

And it helped!
Shred works as it should, make check passes all the test.

Thank you for your help once again.
I have updated the Gentoo bugzilla
http://bugs.gentoo.org/show_bug.cgi?id=130246
now I am waiting for the patched version to appear in Gentoo repository.

Best regards,
Adam
