Why do the most obvious things elude me at times ?
This problem returns with gcc 4.2.2.

you compiled, but you didnt execute. compiling it doesnt really test us anything.

Hi, According to SpanKY comment, my environment is safe. However, I still not able to compile clamav. What do I need in order to be able to upgrade? Thank you.

Igor, please test the patch which I am about to attach. Here's how to apply it and re-install gcc: 1) ebuild gcc-3.4.6-r2.ebuild unpack 2) cd /var/tmp/portage/sys-devel/gcc-3.4.6-r2/work/gcc-3.4.6 3) patch -p1 < /path/to/gcc-3.4.6-PR28405.patch 4) cd - 5) ebuild gcc-3.4.6-r2.ebuild compile 6) ebuild gcc-3.4.6-r2.ebuild install 7) ebuild gcc-3.4.6-r2.ebuild qmerge Afterwards, ensure that gcc-3.4.6 is the active compiler (not forgetting to source /etc/profile) and try to build clamav again.
Created attachment 173919 [details, diff] gcc-3.4.6-PR28405.patch
Oops, the filename should have contained "PR28045" rather than "PR28405". Not that it particularly matters.
Never mind, I fail. I had a recollection of this bug revolving around gcc-3.4.6 but should have reviewed again (shouldn't really post on bugs in the early hours, obviously). That said, the fix is still applicable to that branch. Regarding the 4.x branch, the bug was discovered shortly after the release of gcc-4.1.1 so, in theory, >=4.1.2 is supposed to be OK. > I have gcc-4.1.1 which does _not_ have this bug. Are you saying that you don't believe that gcc-4.1.1 is subject to the PR28045 bug or that you didn't encounter the bug when using gcc-4.1.1? The gcc-4.1.1 sources definitely do not contain the fix so, unless gentoo backported the patch at some point, it should be expected to fail. In other words, please upgrade gcc to the latest stable version (that's 4.1.2) and try again. On the other hand, if clamav fails in >=4.1.2 then perhaps it has a faulty test case.

The thing is, when I tried to compile the test program pr28045.c, nothing happened. Compilation didn't fail. That's why I said I don't have this bug... Thank you.
Also, Kerin, are you saying that this patch will fix the problem if applied to my version of gcc (4.1.1)? Thank you.
> The thing is, when I tried to compile the test program pr28045.c, nothing > happened. Compilation didn't fail. That's why I said I don't have this bug... I understand. But gcc-4.1.1 is confirmed to have this problem - at least the vanilla version is (see below). Therefore, there doesn't appear to be a good reason to doubt clamav's assertion in this particular case. > Also, Kerin, are you saying that this patch will fix the problem if applied to > my version of gcc (4.1.1)? Yes, on the basis that the patch was applied to gcc mainline _after_ the release of 4.1.1. You can verify this for yourself by unpacking the gcc-4.1.1 tarball and checking the relevant function in gcc/fold-const.c and also by checking the date upon which the original patch was submitted by Richard Guenther. The only way it could have been truly fixed within the scope of that release is for gentoo to have included it in their bespoke gentoo patchset in a subsequent revision bump. However, I'm too lazy to download the relevant files (which have expired from the gentoo mirrors anyway) and check ;) Bear in mind that the patch I attached was generated against gcc-3.4.6, but will most likely apply against gcc-4.1.1 with fuzz. If not, it's trivial to apply by hand. Or you could just upgrade to 4,1.2 ... The original patch is here: http://gcc.gnu.org/ml/gcc-patches/2006-06/msg01000.html and it appears to be accompanied by an official testcase. In any case, the above statements can be proved or disproved by your testing the patch.
my guess is you're actually hitting a sandbox bug. if you're affected, try upgrading to sandbox-1.3.1 and see if the error goes away.

no

Igor: you arent using stable gcc (which is 4.1.2). upgrade to stable. since things are fixed for people running latest stable or unstable, close it.
