[Gdal-dev] Floating point exception on x86_64

I've been a quasi daily user of gdal for the last three years on x86. For the
last week, I've been trying to use gdal-1.26 on two 64b machines, a Mobile
AMD64 and a P4_E64. Both machines run Gentoo. I first used the gentoo ebuild.
On both machines, installation works, gdal-config works properly, and I'm
able to use the GRASS 'r.in.gdal' with success.
However, gdalinfo, gdalwarp, ogrinfo ... all crash with a floating point
exception (even with as simple as a --help as flag). A dmesg gives me (for
gdalinfo trap divide error rip:3682a0811d rsp:7fffffffe900 error:0
gdalwarp trap divide error rip:3682a0811d rsp:7fffffffe910 error:0
ogrinfo trap divide error rip:3682a0811d rsp:7fffffffe910 error:0
Here are my regular CFLAGS and FFLAGS
CFLAGS="-march=k8 -O2 -pipe -fweb"
FLAGS="-march=k8 -O2 -pipe -fweb"
On top of that, I have 'pic' in my USE flags (for non-gentooer, that puts an
additional -fPIC to the flags when needed).
Compiling the sources 'by hand' leads to the same (absence of) results. Same
thing with 1.2.5
Any idea/comment/suggestion would be more than welcome, a GIS without gdal
isn't really worth
Thx in advance
