It crashes in proj.4. But the lines mentionned are weird : pj_free (pj_init.c:496). At line 496 of pj_init.c, this is not the pj_free() function. Perhaps due to optimizations that mess up line reporting. I tried with proj 4.9.3 and it works fine for me. I see from https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/gdal that archlinux doesn't build with GDAL with --with-static-proj4, so I'm wondering if there isn't a mix of proj.4 versions. Isn't there a chance that one of the dependencies of GDAL links against a libproj.so.X (spatialite could be a good candidate) and that GDAL then loads a libproj.so that is a symlink to libproj.so.Y Can you check your /usr/lib/libproj.so* files ?
