Never seen anything like this before:

Any thoughts about what I should do or check? I have tested the memory thoroughly (for no specific reason other than I like to test things :) ), although that was about a year ago. |

It's not likely to be a real hardware memory issue unless you're seeing other random failures, segfaults, freezes etc. Especially if your problem is repeatable. The most likely cause is a package (library) update where reverse dependencies needed a rebuild, but for some reason that rebuild didn't happen.
First line of attack is check your recent emerge logs and make sure you've followed all the instructions there. Second line is a revdep-rebuild. Third line is to rebuild gm, ie. emerge -1 graphicsmagick. If none of that works, you can try rebuilding all of gm's dependencies.
Here's how I'd do that last one (I don't claim this is the best way, but it should work). I'm using /usr/bin/convert (part of imagemagick) as an example, as I don't have graphicsmagick installed)...
First get a list of all the packages linked by /usr/bin/convert:
| Code: | $ qfile -qC -e $(ldd /usr/bin/convert | cut -f 3 -d ' ') | sort -u | tee /tmp/xx
app-arch/bzip2-1.0.6
media-gfx/imagemagick-6.6.5.6
media-libs/freetype-2.4.4
media-libs/jpeg-8b
media-libs/lcms-2.0a
media-libs/tiff-3.9.4-r1
sys-apps/util-linux-2.19.1
sys-devel/gcc-4.4.5
sys-devel/libtool-2.2.10
sys-libs/glibc-2.11.3
sys-libs/zlib-1.2.5-r2
x11-libs/libICE-1.0.7
x11-libs/libSM-1.2.0
x11-libs/libX11-1.4.3
x11-libs/libXau-1.0.6
x11-libs/libxcb-1.7
x11-libs/libXdmcp-1.1.0
x11-libs/libXext-1.2.0
x11-libs/libXt-1.1.1 |
Now edit the list and cull stuff that really shouldn't need rebuilding (glibc, libtool, gcc, probably perl, python, ruby too if they appear). Also stick an = at the front of each line so the list works as arguments to emerge:
| Code: | $ vi /tmp/xx
$ cat /tmp/xx
=app-arch/bzip2-1.0.6
=media-gfx/imagemagick-6.6.5.6
=media-libs/freetype-2.4.4
=media-libs/jpeg-8b
=media-libs/lcms-2.0a
=media-libs/tiff-3.9.4-r1
=sys-apps/util-linux-2.19.1
=sys-libs/zlib-1.2.5-r2
=x11-libs/libICE-1.0.7
=x11-libs/libSM-1.2.0
=x11-libs/libX11-1.4.3
=x11-libs/libXau-1.0.6
=x11-libs/libxcb-1.7
=x11-libs/libXdmcp-1.1.0
=x11-libs/libXext-1.2.0
=x11-libs/libXt-1.1.1 |
Then rebuild. Emerge will make sure the build order is correct. Make sure you use -1 arg to emerge so those libs don't get into your world file:
| Code: | $ emerge -1p $(cat /tmp/xx)
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-libs/zlib-1.2.5-r2

If you've still got the problem, you've probably hit a bug. You could try downgrading graphicsmagick, or upgrading to a testing version. |
